Heat Transfer

Front

What is thermal equilibrium?

Back

The concept in which two objects in contact with each other transfer heat until they are equal in temperature.

Front

How does warm air compare to cold air in terms of density?

Back

Warm air is less dense than cold air.

Front

What is convection?

Back

The transfer of heat in a fluid (gas or liquid) by means of up and down movements through currents.

Front

What process occurs when an ice cube melts on a hot surface?

Back

Conduction, the transfer of heat from the hot surface to the ice cube.

Front

What happens to the movement of molecules when heat is added to an object?

Back

The molecules move faster.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What is an example of convection in everyday life?

Back

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

Front

What is the main difference between conduction and convection?

Back

Conduction occurs in solids through direct contact, while convection occurs in fluids through movement.

Front

What is the role of thermal energy in heat transfer?

Back

Thermal energy is the energy that comes from the temperature of matter, and it is transferred between objects.
