Changes of State Changes in Thermal Energy

Which phrase describes the changes that take place when a gas condenses?

• Which phrase describes the changes that take place when a gas condenses?

• gain of energy and increased freedom of particle motion

• loss of energy and decreased freedom of particle motion

• gain of energy and decreased freedom of particle motion

Frost forms when water vapor changes directly from a gas to ice. If you were to model the water particles before and after this process, how would they compare?

• Before the process, the particles vibrate in place; after the process, they slide by each other.

• Before the process, the particles slide by each other; after the process, they vibrate in place.

• Before the process, the particles vibrate in place; after the process, they move quickly in all directions.

• Before the process, the particles move quickly in all directions; after the process, they vibrate in place.

Which energy transfer takes place when water freezes to form ice crystals in the atmosphere?

• Energy is transferred from the air into the water.

• Energy is transferred from the water into the air.

• . Energy is transferred from the water into the ground.

• Energy is transferred from warmer ice crystals to colder ones.

How does thermal energy play a role in particle motion and changes of state?

• Thermal energy is a term that refers to temperature

• Increasing an object's thermal energy increases particle motion and can cause a change of state.

• Decreasing an object's thermal energy increases particle motion and can cause a change of state.

• Thermal energy is the energy added from a heat source.
