Specific Heat Practice

Front

What does a high specific heat mean?

Back

It requires more energy to change temperature.

Front

What is the change in temperature when aluminum foil cools from 100° to 50°?

Back

50°

Front

Which material requires more energy to raise the temperature by 1ºC: Water (4184 J/gºC) or Wood (1760 J/gºC)?

Back

Water.

Front

How does heat flow?

Back

Always from warm to cold.

Front

Which has a higher specific heat capacity: Water or Sand?

Back

Water.

Front

Define specific heat capacity.

Back

The amount of heat energy required to raise the temperature of 1 gram of a substance by 1ºC.

Front

What is the specific heat capacity of water?

Back

4184 J/gºC.

Front

What is the specific heat capacity of aluminum?

Back

900 J/gºC.

Front

If a substance has a low specific heat capacity, what does that imply about its temperature change?

Back

It heats up quickly with energy added.

Front

What is the formula for calculating heat energy (Q)?

Back

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