(Chapter 2) Thermal Energy Review (Amplify)

Front

What occurs when objects collide with each other?

Back

Energy transfers occur.

Front

What happens to thermal energy as the number of molecules in an object increases?

Back

The more thermal energy it has.

Front

What happens to the molecules in solid ground when lava flows over it and increases the temperature?

Back

The energy of the molecules in the ground increases.

Front

True or False: Molecules move at the same speed no matter what the temperature.

Back

False.

Front

From where to where does energy transfer occur?

Back

Energy will always be transferred from the hotter sample to the colder sample.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the molecules in an object.

Front

How does temperature relate to the movement of molecules?

Back

As temperature increases, molecules move faster.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred due to a temperature difference.

Front

What happens to the thermal energy of an object when it is heated?

Back

The thermal energy increases.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact.
