Temperature
This temperature scale is used in most countries outside the United States.
Celsius
What happens to the size of most materials when they are heated?
Size increases
This type of heat transfer is related to direct contact.
Conduction
This is the total kinetic energy of all the particles in a substance.
Thermal energy
A material that easily transfers heat is called this.
Conductor
This temperature scale is used by scientists and its units are "K".
Kelvin
A hot air balloon will rise and fly because of hot air. This is an example of what?
Thermal expansion
Heat transfer through the movement of liquid or gas is called this.
Convection
This is the average kinetic energy of the particles in a substance.
Temperature
A blanket is an example of this.
Insulator
This is the freezing point of water in degrees Fahrenheit.
32 O F
Rubber tires shrinking in the cold is an example of what?
Thermal contraction
Getting a sunburn is an example of this type of heat transfer.
Radiation
What happens to the thermal energy of a substance when it is heated?
It increases
Name a good conductor of heat.
*TEACHER DECISION* (Metal, copper, silver, etc.)
This is the boiling point of water in degrees Celsius.
100 O C
What happens to particles when they are cooled?
They slow down and come closer together
A pancake cooking on a stovetop is an example of this type of heat transfer.
Conduction
Which state of matter has the highest amount of thermal energy?
Gas
Name a good insulator of heat.
*TEACHER DECISION* (Wood, rubber, fabric, etc.)
What tool do we use to measure temperature?
Thermometer
A metal lid is stuck on a glass jar. Explain how you could use thermal expansion or contraction to help loosen it.
Run hot water over the lid, as metal expands, the lid will become loose and the lid will open easier.
Convection moves in this type of motion.
Circular (in a circle)
What are the two units you can use to measure thermal energy?
Calories and Joules
Why is it a good idea to use an oven mitt when baking?
*TEACHER DECISION* (The oven mitt is an insulator, so your hand does not burn)
