Thermal Energy Lesson 7-14 Review

Front

What happens to food coloring dropped in a cup of hot water?

Back

It will spread out quickly due to the thermal energy of the hot water.

Front

What happens to ice cubes in hot water?

Back

The thermal energy from the water is given to the ice, causing it to melt while the water cools down.

Front

Which type of matter has the fewest particle collisions?

Back

Solid has the fewest particle collisions compared to liquids and gases.

Front

True or False: Particles give each other heat energy when they bump into each other.

Back

True.

Front

How does heat transfer between particles?

Back

Heat transfers when particles collide with each other.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What happens to the temperature of ice when it melts in warm water?

Back

The temperature of the ice increases as it absorbs thermal energy from the warm water.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.
