Specific Heat Problems

Front

What is specific heat?

Back

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

Front

What is the specific heat of copper?

Back

0.39 J/g °C.

Front

How do you calculate the temperature change (∆t) when heat is added?

Back

∆t = Q / (m * c), where Q is heat added, m is mass, and c is specific heat.

What is the specific heat of aluminum?

Back

0.21 cal/g°C.

Front

How much heat is released when a 10 g piece of aluminum cools from 100°C to 50°C?

Back

105 J.

Front

What is the specific heat of water?

Back

4.18 J/g°C.

Front

How much heat energy moves from 20 g of water when its temperature changes from 25°C to 20°C?

Back

418 Joules.

Front

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

Back

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

What is the amount of energy required to raise the temperature 1ºC for every kilogram called?

Back

Specific Heat.

Front

How does heat flow?

Back

Heat always flows from warm to cold.
