Front

The expansion of matter when it is heated is known as________.

Back

thermal expansion

Front

What happens to the kinetic energy of food particles when they are cooked on a hot grill?

Back

The kinetic energy of the food particles increased, causing the food temperature to rise.

Front

What type of heat transfer occurs when the sun warms a lizard with its electromagnetic waves?

Back

Front

In photosynthesis, solar energy undergoes a ____________ when it changes from light energy to chemical energy.

Back

transformation

Front

How were the hands of a student warmed when using a hand warmer?

Back

Heat was transferred by conduction, resulting in an increase in kinetic energy.

Front

What is thermal energy?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
