Heat and Heat Transfer Review

Front

What is heat transfer?

Back

The movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three main methods of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Define convection.

Back

The transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

What happens to air when it is heated?

Back

It expands and becomes less dense, causing it to rise.

Front

What is thermal energy?

Back

The total kinetic energy of the particles in a substance.

Front

What is kinetic energy?

Back

The energy of motion, which in the context of heat refers to the movement of particles.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the particles in a substance also increases.

Front

What is an example of convection?

Back

Boiling water, where hot water rises and cooler water sinks.
