Kinetic Molecular Theory and Thermal Energy Quiz

What is temperature?

• The transfer of thermal energy as electromagnetic waves

• A measure of the average kinetic energy of particles in a substance

• The movement of thermal energy from one object to another

• The transfer of thermal energy by the circulation or movement of a liquid or gas

What is thermal equilibrium?

• The transfer of thermal energy where heat energy is directly transferred between molecules through collisions or direct contact

• The transfer of thermal energy by the circulation or movement of a liquid or gas

• When two objects transfer heat until they are the same temperature

• The movement of thermal energy from one object to another

What is convection?

• The transfer of thermal energy as electromagnetic waves

• The transfer of thermal energy by the circulation or movement of a liquid or gas

• The movement of thermal energy from one object to another

• A measure of the average kinetic energy of particles in a substance

What is conduction?

• The transfer of thermal energy where heat energy is directly transferred between molecules through collisions or direct contact

• The movement of thermal energy from one object to another

• The transfer of thermal energy by the circulation or movement of a liquid or gas

What is a thermal insulator?

• The transfer of thermal energy by the circulation or movement of a liquid or gas

• A material that transfers thermal energy very poorly

What happens to the particles of an object as it heats up?

• They move faster and spread apart

• They move slower and condense together

• They move in a circular motion

• They move in a straight line

What happens to the particles of an object as it cools down?

• They move in a straight line

• They move faster and spread apart

• They move slower and condense together

• They move in a circular motion

What is thermal expansion?

• When heat is removed from a substance, its volume will decrease

• When heat is added to a substance, its volume will increase

• The transfer of thermal energy as electromagnetic waves

• The movement of thermal energy from one object to another
