Specific Heat Physical Science

Front

What is specific heat?

Back

Specific heat is the amount of heat energy required to raise the temperature of 1 kilogram of a substance by 1 degree Celsius (°C).

Front

What is the formula to calculate heat energy?

Back

Front

What unit is specific heat measured in?

Back

Specific heat is measured in Joules per kilogram per degree Celsius (J/kg°C) or J/g°C.

Front

When is the heat energy value negative?

Back

The heat energy value is negative when the sample is cooled or loses heat energy.

Front

Which heats up faster: 100 mL of water or 1000 mL of water?

Back

100 mL of water heats up faster than 1000 mL of water because it has less mass to heat.

Front

What does a higher specific heat indicate about a substance?

Back

A higher specific heat indicates that the substance requires more energy to change its temperature.

Front

What is the specific heat of water?

Back

The specific heat of water is 4184 J/kg°C.

Front

What is the specific heat of wood?

Back

The specific heat of wood is 1760 J/kg°C.

Front

If two substances have the same mass, which one requires more energy to raise its temperature by 1°C: one with a higher specific heat or one with a lower specific heat?

Back

The substance with the higher specific heat requires more energy to raise its temperature by 1°C.

Front

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

Back

When a substance absorbs heat, its temperature increases.
