Energy is measured in


Energy associated with motion is called

kinetic energy

when natural gas heats water, what energy conversion is taking place

chemical energy to thermal energy

When energy is converted, how much energy is destroyed in the process?


The total energy of all the particles in a substance is called?

thermal energy

The more particles a substance has at a given temperature,

the more thermal energy it has

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


heat is measured in what?


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


The transfer of energy by electromagnetic waves is called


heat transfer occurs from cold objects to warmer ones or from warm objects to cold ones

warm objects to cold ones

A material that does not conduct heat well is called

an insulator

the amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin is called its

specific heat

which of the following has the greatest specific heat? aluminum, glass, sand, water


The addition or loss of thermal energy changes the arrangement of the particles during

a change of state

The temperature at which a solid changes into a liquid is called

the melting point

the expanding of matter when it is heated is known as

thermal expansion

Water freezes at 32 degrees on which temperature scale?


Absolute zero is shown as 0 on which scale?


Which of the following is true of the Celsius scale? 0 degrees is absolute zore, 0 degrees is the freezing point ofwter, 32 degreethe freezing point of water.

0 degrees is the freezing point of water

Heated air moves from baseboard heaters to the rest of the room in a process called


which is the best conductor? wood, paper, silver, air


when gasses expand, they fill how much space?

all the space available

a measure of the average kinetic energy of the individual particles in an object is called


A solid is a state of matter that has a indefinite or definite shape? definite or indefinite volume?

definite shape and volume

Particles of a liquid do or do not have close contact with each other and are or are not tightly packed?

they are in close contact with one another but are not tightly packed.

the freezing point of water is the same as its

melting point

Soup is being heated on a stove, and water droplets are forming on the back of the stove. what sequence has occurred?

vaporization then condensation

in cold climates, the amount of snow on the ground may decrease even if the temperature stays below zero degrees Celsius. The process that best describes this event is


In which state of matter are particles packed tightly together in fixed positions?


electromagnetic waves can transfer energy without a(n)


during the convection lab, why did the food coloring placed above the cup with hot water rise to the top?

warm water was less dense

What is the movement of the warm and cold fluid called when it develops the "circular" motion?

convection current

In the radiation lab activity, what was the dependent variable?

the temperature change of each substance

The transfer of thermal energy from one substance to another through direct contact is?


The handle of a metal spoon warms up when it is placed in a hot bowl of soup because of


One possible cause of tectonic plate motion is the rise of hot material from deep within the Earth while cooler material near the surface sinks. As this process repeats, it is an example of


The transfer of energy by electromagnetic waves is called


A measure of the average kinetic energy of the individual particles in an object is called


In the Leslie cube experament, what was the dependent variable?

the temperature

Which of the following surfaces would absorb heat most rapidly? shiny black, shiny white, dull black, dull white, shiny black

dull black

Which of the following was the worst conductor? steel copper air or diamond


What method of heat transfer is demonstrated by the sun heating the Earth?


What method of heat transfer is demonstrated by a hot air balloon rising?


What method of heat transfer is demonstrated by you being warmed, sitting near a fire?


Which of the following temperatures is the highest? 100 degrees C, 100 degrees K, 100 degrees F, or they are all the same?

100 degrees C

During conduction heat is transferred by the movement of currents within a fluid.

false, that is convection

Trapped air is a good conductor because it reduces heat transfer.

false, it is a good insulator

Particles of matter in the solid state are held together but can move around each other.

false, they cannot move around each other

A substance gains thermal energy as it freezes.

false, it decreases

A change in the thermal energy of an object is related to the objects specific heat, temperature change, and mass.


Particles in a liquid move around just as freely as particles in a solid.

false, they do not
