Energy that an object has because of its motion is called kinetic energy.

The total kinetic energy of the particles in a substance is called ___________

The measure of the average kinetic energy of the particles in a substance is called temperature.

________ is the ability to do work.

The ability of a substance's particles to move slower and contract without changing states is called thermal expansion.

Almost every substance _________ when heated and _________ when cooled.

Temperature is usually measured in degrees Fahrenheit or Celsius.

A ________ is the amount of thermal energy needed to raise the temperature of 1g of water 1 degree.

The thermal energy of a substance is determined by its temperature and mass.

Heating a substance add thermal energy and the particles move ________ and farther apart, causing the substance to change states.

Cooling a substance causes it to gain thermal energy. The particles move faster and are attracted to each other more, causing the substance to change states.

When particles in a substances move ________ the temperature increases.

If a substance has a higher temperature, it has less thermal energy.

The transfer, or movement, of thermal energy from one substance to another is called ________________

Heat always flows from a ________ substance to a _________ one.

Occurs when particles of substances bump into and touch each other.

Occurs when particles of a substance carry thermal energy as they move from one place to another.

Occurs when there are no particles to carry the energy.

Can occur through empty space

Usually occurs in liquids and gases.

All of these are examples of conduction except...

Solids are usually heated by conduction.

Energy is any substance that releases energy when it burns.

Convection can occur in empty space.

___________ is an important source of heat and light for the earth.

Substances that allow heat to move through them easily are called _________.

Substances that do not allow heat to move through them easily are called conductors.

All of the following are insulators except ___________

_________ are caused by heated particles rising while cooler particles sink. Those particles get heated and rise while the ones at the top that have cooled off sink. The process continually repeats.

Convection usually occurs in all of these except __________

Fossil fuels formed when the remains of plants and animals were buried quickly during the Genesis flood.

All of these are fossil fuels except ___________

When a warmer substance transfers heat to a cooler substance, the cooler substance ________ thermal energy and the warmer substance ________ thermal energy.

Heat transfer that occurs when there are no particles to carry the energy is called ___________

Heat transfer that occurs when particles of a substances bump into or touch each other is called convection.

Heat transfer that occurs when particles of a substance carry thermal energy as they move from one place to another is called _________-

Cooking on a stovetop or eating a popsicle usually involves this kind of heat transfer ________

Boiling water or heating a room usually involves conduction.
