Heat Transfer and Thermal Energy

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

A type of heat transfer that occurs through direct contact between materials, where heat is transferred through particle collisions.

Front

Define convection.

Back

A type of heat transfer that occurs in fluids (liquids and gases) where warmer, less dense regions rise and cooler, denser regions sink, creating a circulation pattern.

Front

Define radiation.

Back

A type of heat transfer that does not require a medium; it occurs through electromagnetic waves, such as infrared radiation.

Front

What is the best conductor of heat?

Back

Metal is the best conductor of heat due to its free-moving electrons.

Front

What is an insulator?

Back

A material that does not conduct heat well, preventing heat transfer; examples include wood, glass, and plastic.

Front

What is the Zeroth Law of Thermodynamics?

Back

It states that if two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other, providing a basis for measuring temperature.

Front

What is thermal equilibrium?

Back

A state in which two objects in contact with each other do not exchange heat, meaning they are at the same temperature.

Front

What is specific heat capacity?

Back

The amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.
