States of matter
This state of matter has has no fixed shape and volume.
gas
what is the change from solid to liquid?
melting
definition for condensation.
the process by which a gas changes state to become a liquid.
The molecules in a gas move __________ than the molecules in a liquid.
Faster
The phase change that occurs when a solid changes to a liquid.
Melting
This occurs when molecules that make up a substance experience a change to their freedom of movement and a the substance changes appearance.
phase change
what is the process by which a liquid turns to gas
Evaporation
What is the process of evaporation
liquid→gas
The energy that an object has because it is moving
kinetic energy
What is the phase change when a liquid turns into a gas?
Evaporation
what is the state of matter which has both fixed volume and shape
solid
Describe how water molecules move when they are boiling.
Fast or rapidly
what is the definition for deposition
When a gas becomes a solid directly
This is a measure of the average kinetic energy of the molecules of a substance
temperature?
This is the type of phase change that occurs when a gas turns into a solid.
Deposition
what are the 4 different states of matter
solid, liquid, gas, and plasma
Give 2 example of a liquid turning into a gas
evaporation and boiling
What is Exothermic and Endothermic?
Exothermic=Freezing
Endothermic=melting
Heating a substance increases this form of energy in the molecules of the substance
Kinetic Energy
This is the phase change when a solid turns into a gas
A noticeably different form or state of the same substance
phase
How are boiling, evaporation, and sublimation related?
all of them are changes to gases
what is the vocab word: have a very orderly , three-dimensional arrangement of atoms or molecules. Particles repeat in patterns or rows.
Crystalline
The more kinetic energy a substance, the greater the ______________________ the molecules have.
freedom of movement
A substance with greater molecular attraction will _______ into a solid at a higher temperature than a substance with lower molecular attraction.
