Physical Science SPS7: Energy Review

Front

What is the formula to calculate heat energy gained or lost?

Back

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

Front

What is specific heat?

Back

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

Front

What type of energy does a television transform electrical energy into?

Back

A television transforms electrical energy into light energy and sound energy.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a process that releases heat to its surroundings.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often used for cooking and heating.

Front

What is the change called from a liquid to a gas?

Back

The change from a liquid to a gas is called vaporization.

Front

What is the specific heat of copper?

Back

The specific heat of copper is 390 J/kg °C.

Front

What happens during condensation?

Back

During condensation, a gas turns into a liquid, releasing heat energy.

Front

What is the process of freezing?

Back

Freezing is the process where a liquid turns into a solid, releasing heat energy.

Front

What is the process of deposition?

Back

Deposition is the process where a gas turns directly into a solid, releasing heat energy.
