11D Specific Heat Calculations

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Front

What is the formula to calculate heat energy (Q)?

Back

Q = mc∆t, where m is mass, c is specific heat, and ∆t is the change in temperature.

Front

If a substance has a high specific heat, what does that mean?

Back

It means the substance requires more energy to change its temperature.

Front

What is the average kinetic energy of particles in a substance related to?

Back

It is related to the temperature of the substance.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases.
