Thermal Energy/ Transfer, Specific Heat, Gas Laws

Front

What happens to liquids when they are heated?

Back

Liquids expand when heated and contract when cooled.

Front

What is the energy needed to heat up 1kg of a substance by 1K called?

Back

Specific heat.

Front

What happens to the volume of a gas when it is cooled?

Back

The volume will decrease.

Front

How do hot objects begin to cool?

Back

Thermal energy in the object is transferred to the surrounding air.

Front

When you touch a hot stove, where does the heat transfer?

Back

From the stove to your hand.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the 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 and gases).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.

Front

What is the formula for calculating specific heat?

Back

Specific heat = Heat energy / (mass × temperature change).
