Thermal Energy Transfers & Conductivity

Front

What happens to the particles in matter as temperature increases?

Back

The particles move faster.

Front

What is convection?

Back

Convection is the primary way heat travels through liquids and gases.

Front

What occurs when energy is added to matter?

Back

The particles move faster and farther apart.

Front

How does heat energy transfer from a hot rock to cool water?

Back

Through conduction.

Front

Why is sand at the beach hotter than water?

Back

Sand has a lower specific heat than water.

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 current?

Back

A convection current is a flow that transfers heat through a fluid (liquid or gas) due to differences in temperature and density.

Front

What is specific heat?

Back

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

Front

What is radiation?

Back

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