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?
This occurs when molecules that make up a substance experience a change to their freedom of movement and a the substance changes appearance.
The energy that an object has because it is moving.
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 kinetic energy of the molecules of a substance.
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.
Heating a substance increases this form of energy in the molecules of the substance.
What is kinetic energy?
As atoms vibrate 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?
The fourth phase of matter has higher energy than gas
What is a plasma?
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 does vaporization mean in relation to phase changes?
