Specific Heat

Front

What is specific heat?

Back

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

Front

Which object heats up faster: one with a higher specific heat or one with a lower specific heat?

Back

An object with a lower specific heat will heat up faster.

Front

What are the SI units for specific heat?

Back

The SI units for specific heat are J/g°C or J/kg°C.

Front

What is the formula to calculate heat energy?

Back

Heat energy (Q) = mass (m) × specific heat (c) × change in temperature (ΔT).

Front

What is the relationship between specific heat and temperature change?

Back

A substance with a higher specific heat will experience a smaller temperature change when the same amount of heat is added compared to a substance with a lower specific heat.

Front

What is the unit of heat energy?

Back

The unit of heat energy is calories or joules.

Front

How does specific heat affect climate?

Back

Water's high specific heat helps moderate climate by absorbing and releasing heat slowly.

Front

What is the specific heat of water?

Back

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

Front

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

Back

The temperature of the substance increases as it absorbs heat.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.
