Phase
This holds its shape and does not take the shape of its container.
What happens to the molecules when kinetic energy is transferred into a substance?
What is The molecules of the substance speed up and the substance gets warmer.
Jason has a glass with a substance in it. When he sets it on the cement outside the particles were moving in place. After about ten minutes, Jason returns and the substance's molecules are moving around each other. What change has occurred?
Solid to liquid which is melting.
to provide evidence that does NOT supports a claim.
Refute
a measure of how hot or cold something is.
A substance in this phase has molecules only move in place.
solid
A liquid flows because its molecules __________.
What is move away from each other
Jason has a glass with a substance in it. When he sets it on the cement outside the particles were moving around each other. After about twenty minutes, Jason returns and the substance's molecules moved apart and the substance can not be seen. What change has occurred?
Liquid to gas which is evaporation
This describes the relative size of things.
What is scale
What is melting
Describe the freedom of movement of a solid, a liquid, and a gas.
Solid- molecules move or vibrate in place
Liquid- molecules move around each other
Gas- molecules move apart or away from each other
A phase change occurs when the ________ increases enough to overcome the attraction between molecules.
kinetic energy
Jason brings a very cold sealed jar of ice outside and places it on the cement. In a matter of minutes liquid begins running down the outside of the jar. Where did this liquid come from and what phase change has occurred?
The liquid is from the water vapor that was in the air around the cold jar. Condensation has occurred.
This is a group of atoms joined together in a particular way
What is a molecule
Phase change from a liquid to a gas is called _____.
What is evaporation
This flows and can take the shape of its container.
liquid
A gas does not have a visible shape because gas molecules can _____________________________.
What is move away from each other
Jason has a glass with a substance in it. When he sets it on the cement outside the particles were moving around each other. After about ten minutes, Jason returns and the substance's molecules are moving in place. What change has occurred?
Liquid to solid which is freezing
is a measure of the average kinetic energy of the molecules of a substance.
What is temperature
Phase change from a liquid to a solid is called ________.
What is freezing
This has no visible shape and fills its container.
Gas
What happens when kinetic energy is transferred out of a substance?
The molecules of the substance slow down and the substance gets cooler.
No the candle melting is a phase change because you still have the wax. However the would burning breaks down the wood into new substances so you no longer have wood. So the log burning is not a phase change.
A phase change occurs when the molecules of a substance experience a change to this.
What is freedom of movement
What is condensation
