Specific Heat

Front

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

Which cup has the most thermal energy if all are at the same temperature?

Back

The large cup (Trenta) has the most thermal energy because it contains more mass.

Front

How does heat flow?

Back

Heat flows always from warm to cold.

Front

What is the formula to calculate the change in temperature when heating a substance?

Back

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

Front

What is the specific heat of water?

Back

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

Front

If 200 grams of water is heated from 24.0° C to 100.0° C, what is the change in temperature?

Back

The change in temperature (∆t) is 76 °C.

Front

What is the specific heat of copper?

Back

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

Front

How much heat is required to raise the temperature of 100 grams of water by 10ºC?

Back

Q = m * c * ∆t = 100g * 4.18 J/g °C * 10ºC = 4180 Joules.

Front

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

Back

The temperature of the substance increases.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a substance.
