What is the symbol for Specific Heat?

Back

C

Front

Define 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 for calculating heat energy (Q)?

Back

Q = m * C * ΔT, where m is mass, C is specific heat, and ΔT is the change in temperature.

Front

If a substance has a high specific heat, what does that imply about its thermal properties?

Back

It implies that the substance can absorb a lot of heat without a significant change in temperature.

Front

What is the specific heat of water?

Back

4.18 J/g•°C.

Front

How does the specific heat of metals generally compare to that of water?

Back

Metals generally have a lower specific heat than water, meaning they heat up and cool down faster.
