Amplify Thermal Energy Critical Juncture Mock Asssessment

Front

What happens to the molecules in the countertop when the temperature is increasing?

Back

The energy of the molecules in the countertop increases.

Front

After a while, which of the two top containers will be cooler, and why?

Back

The larger top container will be cooler than the smaller top container. It started with more total energy, so less energy has to transfer for both containers in the stack to reach the same total energy.

Front

Calculate the average kinetic energy of the following diagram.

Back

15 kJ

Front

The 2 objects in the picture are pushed together. How will the energy transfer?

Back

From the top object to the bottom object.

Front

What happened to the molecules in the orange when its temperature decreased?

Back

The energy of the molecules in the orange decreased.

Front

Calculate the average kinetic energy of the diagram.

Back

3 kJ

Front

How does the temperature of the top cube compare with the temperature of the bottom cube before touching, and what will happen when the cubes have been touching for a while?

Back

Before touching, the bottom cube is cooler than the top cube. Once touching, the top cube transfers kinetic energy to the cooler bottom cube until both reach the same temperature, in between their starting temperatures.

Front

Which object is hotter?

Back

Object A because it has the highest average kinetic energy.

Front

What will happen if object A was placed on top of object C?

Back

Object A will warm up Object C by transferring energy to it.

Front

Eric pours some iced tea into a glass. When he puts the iced tea in the glass, the energy of the glass decreases. What must be true of the energy of the iced tea?

Back

The ice tea's energy increases while the energy of the glass decreases.
