Thermal Energy + Thermal Expansion and Contraction

Which type of energy is stored energy due to the interaction between two objects. Hint: Read the question carefully.

Which type of energy is potential energy plus the kinetic energy of an object?

The faster particles move, the less kinetic energy they have.

Which type of energy is when an airplane is up in the air, it is attracted to Earth due to gravity.

Which type of energy is heat energy?

When particles are in motion (moving), they will not have kinetic energy.

The greater the average distance between particles, the less the potential energy of the particles.

Temperature represents the total kinetic energy of the particles that make up a material.

The greater the average kinetic energy of particles, the higher the temperature.

The particles in warmer air move at a greater average speed than the particles in colder air.

On Fahrenheit scale, water freezes at 32 and boils at 212.

ON Celsius scale, water freezes at 0 and boils at 100.

Which type of thermal energy is transferred when thermal energy is being transferred from one material to another by electromagnetic waves?

Which type is the only way thermal energy can travel from the Sun to Earth, because space is a vacuum.

Radiation transfers (passing on) thermal energy (heat) through solids, liquids, and gases.

Warm objects emit less radiation than cold objects do.

When particles with different kinetic energies collide, the particles with higher kinetic energy will not transfer energy to particles with lower kinetic energy.

A thermal conductor is a material through which thermal energy does not flow easily.

A thermal insulator is a material through which thermal energy flows easily.

The amount of thermal energy required to increase the temperature of 1 kg of a material by 1°C is called what?

Thermal expansion is an increase in a material’s volume when its temperature increases.

Thermal contraction is a decrease in a material’s volume when its temperature decreases.
