Specific Heat (Thermochemistry)

Front

What is Specific Heat?

Back

Specific Heat is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

What is the formula for calculating change in Thermal Energy?

Back

Q = mc∆t, where Q is the heat energy, m is the mass, c is the specific heat, and ∆t is the change in temperature.

Front

What does temperature measure?

Back

Temperature measures the average kinetic energy of the particles in a substance.

Front

What is the unit of Specific Heat?

Back

The unit of Specific Heat is J/g°C (Joules per gram per degree Celsius).

Front

If a substance has a high specific heat, what does that imply?

Back

It implies that the substance can absorb a lot of heat without a significant change in temperature.

Front

What is the specific heat of water?

Back

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

Front

How do you calculate the change in temperature (∆t)?

Back

∆t = final temperature - initial temperature.

Front

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

Back

The temperature of the substance increases.

Front

What is the relationship between mass and specific heat in thermal energy calculations?

Back

The greater the mass of a substance, the more heat energy is required to change its temperature.
