Heat transfer by conduction occurs when molecules

flow as currents through liquids

form waves that travel through space

Which example best demonstrates the process of conduction?

C) A metal spoon gets warm when used to stir hot soup.

A) A piece of paper is torn in half.

B) Warmed air rises above a lit candle.

D) Sunlight brightens a dark room.

Which process is most responsible for the temperature changes that will take place?

conduction of heat through the aluminum bar

radiation of heat from the water in the cups to the thermometers

radiation of heat from the water in the cups into the air

conduction of heat through the air to the water in the cups

Over the next 15 minutes, which changes would most likely occur?

The temperature in cup A will decrease and the temperature in cup B will increase.

The temperature in cup A will decrease and the temperature in cup B will decrease.

The temperature in cup A will increase and the temperature in cup B will increase.

The temperature in cup A will increase and the temperature in cup B will decrease.

The normal melting and freezing points for water are

0°C—melting temperature, and 100°C—freezing temperature

100°C—melting temperature, and 0°C—freezing temperature

What occurs when a substance melts?

It changes from solid to liquid, and heat is absorbed.

It changes from solid to liquid, and heat is released.

It changes from liquid to solid, and heat is absorbed.

It changes from liquid to solid, and heat is released.

33. The diameter of a solid metal rod increased slightly after being heated for 5 minutes. What is the reason for this change?

The metal expands when heated due to increased particle movement.

The metal contracts when heated due to decreased particle movement.

The metal loses mass when heated, causing it to shrink.

The metal changes color, which affects its diameter.

Base your answer to the following question on diagrams A and B below and on your knowledge of science. Diagram A represents a glass of water containing ice cubes. As the water and glass cooled, droplets formed on the outside of the glass. Diagram B represents the same undisturbed glass of water two days later. Complete the chart below by identifying the phase change that caused each event. Event: Water droplets formed on the outside of the glass in diagram A. Phase Change: ____________ Event: Ice is no longer visible in diagram B. Phase Change: ____________ Event: The level of water in the glass dropped in diagram B. Phase Change: ____________

Condensation; Melting; Evaporation

Evaporation; Freezing; Condensation

Melting; Condensation; Freezing

State the relationship between the temperature of the metal ball and the speed of the molecules moving in the ball.

As the temperature of the metal ball increases, the speed of the molecules increases.

As the temperature of the metal ball increases, the speed of the molecules decreases.

The temperature of the metal ball does not affect the speed of the molecules.

As the temperature of the metal ball decreases, the speed of the molecules increases.

Describe what can be done so that the metal ball will again go through the ring.

Cool the metal ball to reduce its size.

Heat the metal ball to increase its size.

Paint the metal ball to make it smoother.

Polish the ring to make it larger.

Describe what happens to the molecules and the metal when heat is applied.

The molecules move faster and the metal expands.

The molecules stop moving and the metal contracts.

The molecules move slower and the metal remains unchanged.

The molecules break apart and the metal melts instantly.

The relationship between temperature and molecular motion is that:

As temperature increases, molecular motion increases.

As temperature increases, molecular motion decreases.

Temperature and molecular motion are unrelated.

As temperature decreases, molecular motion increases.

When a metal ball and ring are cooled or heated, what happens to their sizes?

Both expand when heated and contract when cooled.

Both contract when heated and expand when cooled.

Only the ball changes size, the ring does not.

Their sizes remain unchanged regardless of temperature.

Thermal energy always moves:

From a high temperature object to a lower temperature object.

From a lower temperature object to a higher temperature object.

From an object with lower kinetic energy to an object with higher kinetic energy.

From an object of higher mass to an object of lower mass.
