100
Give an example of a solid
Rock, metal, table, etc.
100
What is melting?
When a solid is heated and becomes a liquid
100
Name at least two of the three types of heat transfer
Conduction, convection, radiation
100
Is there a difference between heat and temperature? If so, what is it?
Yes. Heat is the name of the energy that's inside an object and temperature is the measurement about how hot an object is.
100
Which has more heat- an ice cube the size of a house or a hot burning piece of coal? Explain your answer
An ice cube the size of a house because although it is colder, since it is bigger it has more heat energy within it. For this answer, it is essential to remember temperature and heat are NOT the same thing.
200
Give an example of a gas
Steam, Pollution, Fizz (carbonation), etc.
200
What is freezing?
When a liquid becomes a solid
200
What is radiation?
When heat is transferred through electromagnetic waves
200
When something is heated and the molecules move more and spread out, this is called what?
Expansion
200
A heater heating a room is an example of what transfer of heat?
Convection
300
Which state of matter does have volume, but has no shape?
Liquid
300
What is evaporation?
When liquids are heated and becomes a gas
300
What is conduction?
The transfer of heat through objects touching one another
300
When objects are cooled and begin to move closer together, this is called what?
Contraction
300
What is the density of water?
1 g/cm^3
400
Which state of matter has shape AND volume?
solid
400
What is condensation?
When water droplets form on objects when the air cools.
400
What is convection?
Transfer of heat through liquid or air flow
400
Heat moves from hot to cold OR Heat moves from cold to hot
Heat moves from hot to cold
400
The measure of how much mass is in a specific volume is what?? In other words mass/volume = ???
Density
500
Which state of matter does not have shape or volume?
Gas
500
Give an example of when you may see evaporation?
Boiling water
500
What is the BEST example of radiation?
The sun
500
What is the difference between conductors and insulators?
A conductor is an object that easily allows heat to travel through it. An insulator is an object that does not easily allow heat to travel through it.
