Front

What is Thermal Energy?

Back

The total kinetic energy of all the particles in a substance.

Front

What is the formula for calculating Specific Heat?

Back

Specific Heat (C) = Q / (m * ΔT) where Q is heat energy, m is mass, and ΔT is the change in temperature.

Front

What does a high specific heat indicate about a material?

Back

It requires more energy to change its temperature.

Front

What is the specific heat of air?

Back

Approximately 1005 J/KgºC.

Front

What is the relationship between mass and specific heat in thermal energy calculations?

Back

More mass means more energy is required to change the temperature.
