Understanding Evaporation and Boiling

What is the main difference between evaporation and boiling?

• Evaporation occurs at a specific temperature, while boiling happens at the surface.

• The main difference is that evaporation happens at the surface at any temperature, while boiling occurs throughout the liquid at a specific temperature.

• Boiling can happen at any temperature, while evaporation only occurs at high temperatures.

• Evaporation happens throughout the liquid, while boiling only occurs at the surface.

At what temperature does boiling occur for water at sea level?

• 90 degrees Celsius

• 100 degrees Celsius

• 80 degrees Celsius

• 120 degrees Celsius

Can evaporation happen at any temperature? Why or why not?

• Yes, evaporation can happen at any temperature.

• Evaporation only occurs at high temperatures.

• Evaporation can only happen when water is boiling.

• Evaporation is a process that requires a specific temperature to occur.

What is the process called when a liquid turns into a gas?

• Condensation

• Sublimation

• Evaporation or boiling

• Freezing

Describe a situation where evaporation is useful in everyday life.

• Condensing steam in a closed container

• Boiling water for cooking

• Using a humidifier to add moisture

• Drying clothes outdoors using evaporation.

What happens to the temperature of a liquid during boiling?

• The temperature of a liquid fluctuates during boiling.

• The temperature of a liquid remains constant during boiling.

• The temperature of a liquid decreases during boiling.

• The temperature of a liquid increases during boiling.

How does atmospheric pressure affect the boiling point of a liquid?

• Atmospheric pressure lowers the boiling point of a liquid at high altitudes and raises it at high pressures.

• Higher temperatures always increase the boiling point regardless of pressure.

• Atmospheric pressure has no effect on the boiling point of a liquid.

• Boiling point is only affected by the temperature of the liquid.

What is condensation, and how is it related to evaporation?

• Condensation is the process of water vapor turning into liquid water, and it is the opposite of evaporation, where liquid water turns into vapor.

• Condensation occurs when liquid water is heated to form vapor.

• Condensation is the process of water turning into steam.

• Condensation is the process of ice melting into water.

Explain the term 'phase change' in the context of matter.

• Phase change refers to the change in color of an object.

• Phase change is the process of matter becoming radioactive.

• Phase change is the transition of matter between solid, liquid, and gas states.

• Phase change describes the movement of matter in a vacuum.

List the three main states of matter and give an example of each.

• Solid: Wood, Liquid: Milk, Gas: Nitrogen

• Solid: Rock, Liquid: Juice, Gas: Carbon Dioxide

• Solid: Sand, Liquid: Oil, Gas: Helium

• Solid: Ice, Liquid: Water, Gas: Oxygen
