What is Specific Heat?

Back

Specific Heat is the amount of energy required to raise the temperature of 1 kilogram of a substance by 1ºC.

Front

How does heat flow?

Back

Heat always flows from warm to cold.

Front

What is the lowest possible temperature on the Kelvin scale?

Back

The lowest possible temperature on the Kelvin scale is absolute zero.

Front

Which material has the smallest change in temperature when heated with the same amount of thermal energy?

Back

Carbon Steel has the smallest change in temperature when heated with 10,000 JOULES of thermal energy.

Front

What is the specific heat (c) of copper?

Back

The specific heat (c) of copper is 0.39 J/g °C.

Front

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

Back

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

Front

If 100 Joules of heat is added to 20 grams of copper, what is the temperature change?

Back

The temperature change (∆t) is 12.82 °C.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object due to their motion.

Front

What is the relationship between specific heat and temperature change?

Back

A higher specific heat means a smaller temperature change for a given amount of heat added.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which a substance has minimum thermal energy, equivalent to 0 Kelvin.
