Heat and Temperature

Front

What is heat?

Back

Heat is a form of energy that is transferred between objects due to a temperature difference.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is a thermal conductor?

Back

A thermal conductor is a material that allows heat to pass through it easily.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves, such as the heat from the sun or a lamp.

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) caused by differences in temperature.

Front

What happens to particles in a substance when thermal energy is added?

Back

The particles move more rapidly and tend to be further apart from each other.

Front

How does the density of gases compare to that of liquids?

Back

Gases have lower density than liquids because the atoms in gases are further apart.

Front

What is the role of insulation in heat transfer?

Back

Insulation reduces the transfer of heat between objects, keeping heat in or out.

Front

What is the difference between heat and temperature?

Back

Heat is energy transferred due to temperature difference, while temperature is a measure of the energy of particles.
