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.
