Thermal Energy is NOT Temperature

Front

What is thermal energy?

Back

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

Front

How does the number of molecules affect thermal energy?

Back

More molecules in a substance increase its total kinetic energy, leading to higher thermal energy.

Front

What is the difference between thermal energy and temperature?

Back

Thermal energy refers to the total kinetic energy of molecules, while temperature measures the average kinetic energy of those molecules.

Front

What happens to the kinetic energy of molecules when heat is added?

Back

The kinetic energy of the molecules increases, leading to an increase in thermal energy.

Front

What happens to the kinetic energy of molecules when ice is added to a hot liquid?

Back

The kinetic energy of the molecules in the hot liquid decreases as energy is transferred to the ice.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the molecules in a substance.

Front

What is an example of thermal energy in everyday life?

Back

A bowl of soup has thermal energy due to the movement of its molecules.

Front

What is the effect of increasing temperature on molecular motion?

Back

Increasing temperature causes molecules to move faster, increasing their kinetic energy.

Front

What is the role of molecules in determining thermal energy?

Back

The number of molecules and their motion contribute to the total thermal energy of a substance.

Front

What is the effect of cooling a substance on its thermal energy?

Back

Cooling a substance decreases the kinetic energy of its molecules, reducing its thermal energy.
