100
This state of matter has a definite shape and volume.
Solid
100
What is matter?
Anything that has mass and takes up space.
100
Boiling temperature
212 degrees fahrenheit, 100 degrees celcius
100
What is an atom?
smallest building block of life.
100
What is conduction?
Transfer of heat by touching.
200
This state of matter expands to fill the entire container and has no definite shape.
gas
200
What is density?
The amount of space something takes up.
200
freezing temperature
32 degrees farenheit, 0 degrees celcius
200
What is a molecule?
two or more atoms bonded together.
200
What is convection?
transfer of heat by hot air or liquid rising.
300
This state of matter takes the shape of its container and has a definite volume.
liquid
300
Does warm air have higher or lower density? how do you know?
lower density. in Warm air the atoms or molecules are more spread out.
300
During which 2 processes do molecules increase in temperature and the motion of the molecules?
melting and boiling
300
If water is poured from one container to another, what happens to its density?
nothing, it stays the same
300
What is radiation?
transfer of heat by electro magnetic waves
400
changing from liquid to gas? Changing from gas to liquid?
evaporating, condensing
400
What is surface tension?
the bonds on the surface of water that form a bubble and do not want to break.
400
During which phase change is heat add?
solid --> liquid, liquid --> gas
400
What happens when molecules are heated?
They expand and get bigger.
400
Which form of heat transfer is used in a hot air balloon?
convection forces the hot air to rise and the balloon to float.
500
Changing from solid to liquid and liquid to solid.
melting and freezing
500
which is more viscous honey or water? how do you know?
honey is more viscous because it is harder to pour.
500
If you put a thermometer in a pot of melting ice, when will the temperature rise above 0?
When all of the ice has melted.
500
is sound matter? How do you know?
It is not matter because it does not have mass or volume (take up space)
500
Which type of heat transfer does your microwave use?
radiation.
