Heat Capacity & Specific Heat

Front

What is heat capacity?

Back

Heat capacity is the amount of heat energy required to change the temperature of a substance by one degree Celsius.

Front

What is specific heat?

Back

Specific heat is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius.

Front

Why does water have a high specific heat?

Back

Water has a high specific heat due to the hydrogen bonds between its molecules, which require more energy to break.

Front

How does specific heat affect temperature change?

Back

A substance with a high specific heat will experience a smaller temperature change when it absorbs or loses heat compared to a substance with a low specific heat.

Front

What is the specific heat of water?

Back

The specific heat of water is 4.18 J/g°C.

Front

What is the specific heat of wood?

Back

The specific heat of wood is 1.760 J/g°C.

Front

If two substances have the same mass, which will heat up faster?

Back

The substance with the lower specific heat will heat up faster.

Front

What happens to particle motion when heat is added?

Back

When heat is added, the particles in a substance speed up and move more vigorously.

Front

What is the relationship between heat energy and temperature change?

Back

The amount of heat energy added to a substance is directly proportional to the temperature change, depending on the substance's mass and specific heat.

Front

Which material requires more energy to change temperature: water or wood?

Back

Water requires more energy to change temperature due to its higher specific heat.
