What is 37.0 degrees Celsius on the

Fahrenheit scale?

98.6ºF

What is 175ºF on the Celsius scale?

79.4ºC

What is –175ºC on the Kelvin scale?

98 K

As the kinetic energy of the molecules in a

substance increases, the _____ also increases.

temperature

The transfer of energy as heat caused by the

collision of molecules is called

conduction.

The transfer of energy by the movement of fluids or gases with

different temperatures is called

convection.

Energy from the sun reaches Earth by

radiation only.

Convection currents rise in air because

cool air descends and hot air rises.

Which method of energy transfer does not

involve movement of matter?

convection.

radiation.

conduction.

radiation.

How much heat energy will cause the

temperature of 7 kg of carbon to increase its temperature by 15 K?

The specific heat of iron is 449 J/kgK.

4.7 × 104 J(47000 J)

According to the first law of thermodynamics,

the total energy used in any process is

conserved.

In an air conditioner, a substance that easily evaporates and

condenses is used to transfer energy from a room to the air outside. When the substance

evaporates,

it absorbs energy as heat from the surrounding

air.

The Fahrenheit temperature scale is

defined by what temperatures?

Water boils at 212 degrees and freezes at

32 degrees.

The energy transferred between the particles of two objects because of

the temperature difference between the two objects is called

heat

Which of the following substances is the best

conductor of transferring energy as

heat?carbon dioxide gas iron

Water rubber

Iron

Radio waves, infrared radiation, visible light, ultraviolet rays, and X

rays are forms of

electromagnetic waves

A substance used in cooling systems that

transfers large amounts of energy as it changes

state is called a

refrigerant

This is a material through which energy

can be easily transferred as heat.

conductor

This is a material that is a poor energy

conductor.

insulator

This is the amount of energy transferred as heat that will raise the

temperature of 1 kg of a substance by 1 K.

Specific heat

This is any device that transfers energy to a substance to raise the

temperature of the substance.

heating system

This is a device that transfers energy out of an object to lower its

temperature.

cooling system

This is the energy transfer as heat between particles as they collide within a substance or

between two objects in contact.

Conduction

This is the temperature at which an object's energy is minimal.

Absolute zero

This is a device for measuring temperature.
