Chapter 11: Thermal Energy and Heat Study Guide

No more energy can be removed from matter at

absolute zero

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

conduction

The handle of a spoon in a bowl of hot soup becomes warm due to heat transfer by the process of

conduction

As most substances are cooled, they expand.

contract

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

convection

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

convection

A student lists three temperature measurements: 100F, 100C, and 100K. Of the three measurements, 100K is the highest temperature.

false 100 C

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

heat

A material that conducts heat poorly is called an

insulator

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

insulator

The SI unit of heat is the

joule

A one-degree change in temperature on the Celsius temperature scale is equal to a one-unit temperature change on the .... temperature scale.

kelvin

Heat transfer occurs

only from warm objects to colder ones

The transfer of energy by electromagnetic waves is called

radiation

Which of these is a good conductor

silver

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

specific heat

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

temperature

The more particles an object has at a given temperature

the more thermal energy it has

As the thermal energy of matter increases, its particles usually spread out, causing

thermal expansion

The more particles a substance has at a given temperature, the more thermal energy it has.
