Heat Transfer (V)

Front

What is heat transfer?

Back

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

Front

What are the three main types 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 through the movement of fluids (liquids or gases) caused by temperature differences.

Front

Define radiation.

Back

The transfer of energy through electromagnetic waves, which can occur in a vacuum.

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance, often referred to as heat energy.

Front

How does conduction occur in metals?

Back

Metals conduct heat well because their particles are closely packed, allowing energy to transfer quickly through collisions.

Front

What is an example of convection in everyday life?

Back

Warm air rising and cool air sinking, such as in a room heated by a radiator.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin, even when standing in the shade.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of particles, while thermal energy is the total energy of all particles in a substance.
