Amplify Thermal Energy

Front

What happens when a hot and cold sample first come into contact with each other?

Back

Some of the molecules in both samples will have a different kinetic energy.

Front

What occurs when hot and cold air make contact?

Back

The hot air will lose kinetic energy.

Front

Do molecules move at the same speed regardless of temperature?

Back

False.

Front

When will there always be heat transfer between two objects that are touching?

Back

There is a difference in temperature between samples.

Front

Is it true that after two samples achieve equilibrium, the temperature will be 30?

Back

False.

Front

What is thermal energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from a hotter object to a cooler one.

Front

What is conduction?

Back

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