Specific Heat Practice

Front

What unit do you use to measure Thermal Energy?

Back

J

Front

What happens to the particles when more heat is supplied to the system?

Back

They would speed up.

Front

Calculate the heat energy (Q) that moves from 20 g of water with a specific heat of 4.18 J/x°C when the temperature changes from 25° C to 20° C.

Back

418 Joules

Front

The amount of energy required to raise the temperature 1ºC for every gram is called?

Back

Specific Heat

Front

What is the change in temperature when a piece of aluminum foil cools from 100° to 50°?

Back

50°

Front

What is the specific heat of water?

Back

4.18 J/gºC

Front

What is the formula for calculating heat energy (Q)?

Back

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

Front

If 100 g of a substance with a specific heat of 2 J/gºC is heated from 20° C to 30° C, how much heat is absorbed?

Back

1000 Joules

Front

What is the relationship between temperature and kinetic energy of particles?

Back

As temperature increases, the kinetic energy of particles increases.

Front

What does a high specific heat indicate about a substance?

Back

It can absorb a lot of heat without a significant change in temperature.
