8.3 Heat/Specific Heat

Front

What is specific heat?

Back

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

Front

Which material has a higher specific heat: water or sand?

Back

Water has a higher specific heat than sand.

Front

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

Back

It experiences a smaller increase in temperature compared to a substance with a lower specific heat.

Front

What is heat transfer?

Back

Heat transfer is the flow of thermal energy from warmer objects to cooler objects.

Front

How does mass affect temperature change when heating?

Back

A larger mass will experience a smaller change in temperature when the same amount of heat energy is applied.

Front

What is the specific heat of water?

Back

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

Front

Why does sand heat up faster than water?

Back

Sand has a lower specific heat than water, allowing it to heat up more quickly.

Front

What is the relationship between specific heat and temperature change?

Back

The greater the specific heat, the smaller the temperature change for a given amount of heat energy.

Front

What is an example of a material with a low specific heat?

Back

Metals like copper and aluminum have low specific heats.

Front

What is the formula for calculating heat energy?

Back

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