(Molecular attraction of a substance never changes)
Which phase change/process happens in slot canyons where water vapor in the air cools to become flash floods?
What is CONDENSATION?
What is GAS TO A LIQUID?
This phase has no visible shape and fills its container.
What is a GAS?
The molecules in a solid are close together and have no movement.
What is FALSE?
(They move in place)
What happens to the motion of molecules when energy is transferred into a substance?
What is THE MOLECULES MOVE FASTER?
What is KINETIC ENERGY INCREASES?
Whether or not a phase change occurs is determined by the interaction between the _______ energy of the molecules and the ___________ pulling the molecules together.
What is KINETIC.....ATTRACTION?
Which phase change/process happens when heat from volcanically heated rock hits glaciers to form glaciers caves in Iceland?
What is MELTING?
What is SOLID TO LIQUID?
This phase flows and can take the shape of its container.
What is a LIQUID?
A solid changes into a liquid. What happened to the molecules’ freedom of movement?
What is THE FREEDOM OF MOVEMENT INCREASED?
What happens to the motion of molecules when energy is transferred out of a substance?
What is THE KINETIC ENERGY DECREASED?
Liquid A & Liquid B receive the same amount of energy, but only Liquid B becomes a gas. Why?
What is LIQUID B HAD LESS MOLECULAR ATTRACTION?
What is LIQUID B HAD ENOUGH KINETIC ENERGY TO OVERCOME THE MOLECULAR ATTRACTION?
Niagara Falls freezing over is an example of a change that can be seen at which scale?
What is MACROSCALE?

What is YOU WOULD SEE VAPOR/GAS?
What is THE MOLECULES ARE SPREADING OUT/MOVING AWAY FROM EACH OTHER?
A liquid turns into a gas after energy is added. Explain this change using kinetic energy.
What is THE MOLECULES KINETIC ENERGY INCREASED?
What is THE MOLECULES MOVED FASTER AND AWAY FROM EACH OTHER?
