Name a metal that is a good conductor.
Possibilities:
Silver
Aluminum
Iron
Heat transfer occurs only from __________ objects to __________ ones.
Warmer objects to Colder objects.
A material that conducts heat poorly is called a(n) __________________.
insulator
The movement of thermal energy from a warmer object to a cooler object is called _______________.
heat
The transfer of energy by electromagnetic waves is called ___________________.
Radiation
The 3 ways thermal energy is transferred are _____, _____, ______.
Convection, Conduction, Radiation
The 3 states of matter are ____, _____, _____.
solid, liquid, gas
Heated air moves from baseboard heaters to the rest of a room in a process called ___________________.
Convection
Trapped air is a good _______________ because it reduces heat transfer.
Insulator
As the thermal energy of matter ________________, its particles usually spread out, causing thermal expansion.
Increases
During_____________, heat is transferred by the movement of currents within a fluid.
Convection
As most substances are cooled, they _________________.
Contract
A measure of the average ____________ energy of the individual particles in an object is called temperature.
Kinetic
The ___________ particles an object has at a given temperature; the more thermal energy it has.
More
If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the _______________.
Same
True or False. Hot Chocolate can heat the surrounding air.
True
A ________ measures temperature.
Thermometer
This transfers thermal energy between material by collision of particles.
Conduction
State of matter will highest temperature.
Gas
Heat flows from _____ to ______ temperatures.
hot to cold
A one-degree change in temperature on the _________________ temperature scale is equal to a one-unit temperature change on the Kelvin temperature scale.
Celsius
Describe how conductors and insulators differ. Include an example of each.
DOUBLE JEOPARDY!
A material that prevents the flow of energy is called an insulator. A material that permits the flow of energy is called a conductor.
An example of an insulator would be air, wool, plastic, etc.
An example of a conductor would be silver, aluminum, iron, metal
Heat is transferred from one particle of matter to another within an object or between two objects that come in contact is a process called ____________________
Conduction
A student lists three temperature measurements: 100°F, 100°C, and 100 K. Of the three measurements, Which is the highest temperature?
100°C
Joints in train tracks are designed with extra space to allow for __________________ in hot weather.
Thermal Expansion
