States of Matter
This state of matter has has no visible shape and fills its container.
The effects of adding heat are reversible.
What is true?
What phase occurs when the molecules are vibrating in place?
What is a solid?
What occurs when molecules experience a change to their freedom of movement/energy, and the substance changes appearance?
What is a phase change?
Do molecules in solids have energy?
What is true
A substances Kinetic Energy always stays the same
What is false
What is the phase change called when a substance goes from a liquid to a solid?
What is the Freezing point?
This phase of matter holds its shape and does not take the shape of its container.
This is a measure of the average energy of the molecules of a substance.
What is temperature?
When heat is added to atoms, the molecules vibrate much more slowly
What is false?
What phase will a substance be in if it undergoes melting?
What is a Liquid?
This is the reason why a liquid can flow:
What is The molecules have a medium amount of energy and have a medium amount of IMFs or attraction between the molecules. They slide past each other!
Does heating a substance increase or decrease the overall energy?
What increase?
As atoms move faster, the space between them decreases.
What is false?
If a substance reaches its condensing point, what phase is it leaving, and what phase is it becoming?
What is a gas and a liquid?
What is sublimation?
The more kinetic energy a substance, the less ______________________ the molecules have.
What is Intermolecular forces or attraction?
When atoms are heated, they increase their kinetic energy as they collide into one another
What is true
What happens during vaporization/boiling in relation to phase changes?
During vaporization, a substance reaches its boiling point, and liquid will then become a gas.
