What is the difference between the particle/molecule movement in a gas and the particle/molecule movement in a liquid?

Particles in a gas are spread far apart and move quickly, while particles in a liquid are closer together and move past each other.

Particles in a gas move very slowly, while particles in a liquid move quickly.

Particles in a gas are tightly packed and do not move, while particles in a liquid move freely.

Particles in both gas and liquid move in the same way, only at different speeds.

How does convection cause the water in a pot to heat up evenly?

A) The hot water rises, while cooler water sinks, creating a circular motion that helps heat spread evenly throughout the pot.

B) Heat travels in straight lines and heats only the top of the water.

C) Convection does not affect the movement of water.

D) The hot water stays at the bottom of the pot and does not mix with cooler water.

If you heat a metal spoon in a pot of hot soup, how does the heat travel from the soup to the spoon? What type of heat transfer is this?

The heat travels by conduction because the soup and the spoon are in direct contact.

The heat travels by convection because the soup moves around the spoon.

The heat travels by radiation because heat is transferred through waves.

The heat travels by evaporation because the soup is boiling.

What happens to the particles/molecules in a substance when it is heated, and how does this relate to the temperature?

The particles move faster, causing the temperature to increase.

The particles slow down, and the temperature decreases.

The particles stay the same and the temperature stays the same.

The particles stop moving, and the temperature becomes the same.

What happens to the particles/molecules during a phase change?

During a phase change, heat is absorbed or released, causing the particles to move closer together or farther apart.

During a phase change, heat is absorbed or released, and the particles stay the same, just moving faster or slower.

During a phase change, the particles stay the same temperature, but they change their shape.

During a phase change, heat is absorbed, and the particles stop moving entirely.

What is evaporation, and how does it fit into the water cycle?

Evaporation is when water turns into gas and rises into the air.

Evaporation is when water falls from the sky as rain.

Evaporation is when clouds form in the sky.

Evaporation is when water soaks into the ground.

What happens when water vapor cools and forms tiny droplets?

Water vapor cools and forms tiny droplets, creating clouds.

Water turns into gas and rises.

Water falls to the ground as rain or snow.

What is precipitation, and how does it affect the Earth's surface?

Precipitation is water that falls from the sky, such as rain or snow.

Precipitation is the process of water soaking into the soil.

Precipitation is the movement of water through rivers.

Precipitation is when water turns into gas and rises into the atmosphere.

What is runoff, and how does it contribute to the movement of water across the land?

Runoff is water that moves over the surface of the Earth and eventually flows into rivers and lakes.

Runoff is water that evaporates into the air.

Runoff is water that is absorbed by plants.

Runoff is water that soaks deep into the ground.

How does runoff contribute to flash floods?

Runoff can cause flash floods because the water can't infiltrate the ground and the water moves quickly to the lowest point.

Runoff carries water to the ocean where it evaporates.

Runoff helps prevent flash floods by soaking into the ground.

Runoff turns into clouds that cause rainstorms.

In places like Las Vegas, why do flash floods often occur after a heavy rainstorm?

The ground is dry and unable to absorb a lot of water quickly, leading to runoff and flash floods.

Las Vegas has no precipitation, so floods are rare.

There is too much evaporation, which causes flooding.

Water vapor rises and stays in the air, causing the rain to last longer.

What happens when the ground is already saturated with water, and it can’t absorb any more?

Runoff increases and can lead to flash floods.

Water begins to evaporate quickly.

Water soaks deeper into the ground.

The water forms clouds and causes more precipitation.

If you were to create a model of the water cycle, how would you show evaporation, condensation, precipitation, runoff?

Draw a cycle with arrows showing how water moves from the ground to the atmosphere and back.

Draw a line of clouds and label them with the word "precipitation."

Draw only the rain falling from the sky and call it the water cycle.

Draw a picture of the ocean and label it as evaporation only.

Evaporation is when water turns into gas and rises into the air.

Evaporation is when water falls from the sky as rain.

Evaporation is when clouds form in the sky.

Evaporation is when water moves across rivers.

What is precipitation, and how does it affect the Earth's surface?

Precipitation is when water falls from the sky as rain, snow, or hail.

Precipitation is when water turns into gas and rises into the atmosphere.

Precipitation is when water is absorbed by plants.

Precipitation is when water soaks into the ground.

How does infiltration happen, and why is it important for the water cycle?

Infiltration is when water soaks into the ground, helping to replenish underground water supplies.

Infiltration is when water turns into gas and rises into the air.

Infiltration is when water falls to the ground as rain or snow.

Infiltration is when water moves over the land as runoff.

How does runoff contribute to flash floods?

Runoff can cause rivers and streams to overflow, especially when the ground cannot absorb water quickly, leading to flash floods.

Runoff carries water to the ocean where it evaporates.

Runoff helps prevent floods by soaking into the soil.

Runoff turns into clouds that bring more rain.

In places like Las Vegas, why do flash floods often occur after a heavy rainstorm?

The ground is dry and hard, so it can’t absorb much water quickly, causing runoff to build up and lead to flash floods.

Las Vegas has no precipitation, so floods are rare.

Las Vegas has very few clouds, so flooding is uncommon.

The ground is always wet, so runoff never happens.

If you were to create a model of the water cycle, how would you show evaporation, condensation, precipitation, runoff, and infiltration?

Draw a simple cycle with arrows showing how water moves from the ground to the atmosphere and back.

Draw only the rain falling from the sky and call it the water cycle.

Draw a picture of the ocean and label it as evaporation only.

Draw only the clouds and call it condensation.

If enough heat was removed from B, it will change state. Which of the following would be true if this happens?

It would become a solid through the process of solidification.

It would become a solid through the process of condensation.

It would become a gas through the process of evaporation.

It would become a gas through the process of melting.

An ice cube melts in a glass of water because _________.

heat energy flows from the water into the ice cube

all the cold energy leaves the ice cube

all the heat energy leaves the ice cube

heat energy flows from the ice cube into the water

You have decided to start sealing all your letters with glittery wax because you are so cool. Which answer BEST explains what you must do to make the SOLID wax a LIQUID?

In order to make the SOLID wax a LIQUID you must ADD HEAT ENERGY by putting the wax over a FLAME.

In order to make the SOLID wax a LIQUID you must ADD HEAT ENERGY by putting the wax in the FREEZER.

In order to make the SOLID wax a LIQUID you must REMOVE HEAT ENERGY by putting the wax in an OVEN.

Which will most likely occur when raw egg is placed on black pavement o n a hot, summer day?

The pavement will conduct the heat and cook the egg.

The egg will reflect the heat and make the pavement hotter underneath.

The egg will absorb the heat and leave the pavement h otter underneath.

The pavement will absorb the heat from the egg, and the egg will stay raw.

5. Nasha left a hot bowl of soup in a cool room. Her friend tells her that her soup will get cold if she forgets to eat it. How cold could it get?

Only as cold as the temperature of the room. It will stop cooling down when it is exactly the same temperature as the room.

Only a little colder. It started out much hotter, so it will stop cooling down before it reaches the same temperature as the room.

Only a little colder. It will stop cooling down when its temperature is about halfway between its starting temperature and the temperature of the room.

Colder than the temperature of the room. It will keep cooling down for as long as she leaves it in the room.
