Chemistry: Heat Transfer P2

Front

What is the total energy (kinetic & potential) of all the particles in a substance called?

Back

Thermal energy

Front

Why do mittens help keep your hands warm in winter?

Back

They are insulators which helps keep heat from escaping or flowing.

Front

What type of energy is produced when electrical energy is converted?

Back

Thermal energy

Front

What is the measure of average kinetic energy of all the particles within an object called?

Back

Temperature

Front

What is the principle that states energy cannot be created or destroyed, only transformed or transferred?

Back

Law of conservation

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of all particles in a substance, while temperature is the measure of the average kinetic energy of those particles.

Front

What is an insulator?

Back

A material that does not conduct heat well and helps to keep heat from escaping.
