Temperature is

• the transfer of energy from a warm object to a colder object

• scale used by most scientists

• a measure of how hot or cold something is compared to a reference point.

• the type of heat transfer that occurs only in fluids.

The movement of thermal energy from a warmer object to a cooler object is called

• heat.
• temperature.
• motion.
• momentum.

A material that conducts heat poorly is called a(n)

• insulator.
• conductor.
• metal.
• radiator.

Heat is transferred from one particle of matter to another without the movement of matter itself in a process called

• conduction.
• convection.
• radiation.
• insulation.
