phase change 1
solid to liquid
what is melting
the way molecules in a substance move relative to each other?
movement
something we can see with the human eye
visible
what phase change is freezing
liquid to solid
what does liquid molecules do
they move around each other
gas to liquid
condensation
the energy that an object has because it is moving
kinetic energy
what are the 4 steps of a scientific argument
1 a question 2 a claim 3 evidence that supports your claim 4 reasoning
what phase change is melting
solid to liquid
what are the 3 appearances of the solid liquid and gas in the phase change sim
1 solid they move in place 2 a liquid they move around each other 3 gas they separate from each other
liquid to solid
freezing
what are all the phase changes
melting, Freezing, Condensation, Evaporation, Deposition, Sublimation
what element did Robert Boyle use in his pressure vs volume test
mercury
is the energy of condensation transferring in or out and what phase change is it
out and its gas to liquid
what are the appearances of a gas in the phase change modeling tool
what is 1 it fills its container 2 it has no visible shape 3 it takes the shape of its container
what phase change is condensation?
gas to liquid
a pull between two molecules that is always the same for a substance
attraction
what is another word for burning
combustion
if im squeezing a water bottle is the pressure and volume going up or down
the pressure of the water bottle is going up and the volume is going down
what does gas molecules do in the phase change sim
what is they move apart
what phase change is evaporation
liquid to gas
a measure of how hot or cold something is
temperature
when molecules are at rest
potential energy
what appearences are for a solid in the phase change modeling tool
rigid and it holds its shape
what are the appearances for a liquid in the phase change modeling tool
1 it flows 2 it stays at the bottom of its container
