The level at which we can see things with the naked eye (like an ice cube melting)
Macroscale
The energy an object has because it is moving (the “speed” of molecules)
Kinetic energy
The phase change from a solid to a llquid
Melting
When a gas turns directly into a solid without becoming a liquid first.
Deposition
The specific ”back and forth” motion molecules have when they are stuck in a solid.
Vibrate
The level of atoms and molecules, which is too small to see without a microscope
Molecular scale
A measure of the average kinetic energy of the molecules of a substance
Temperature
The phase change from a liquid to a solid
Freezing
When molecules experience a change to their freedom of movement
Phase change
The ”pull” or “stickiness” that holds molecules together.
Molecular attraction
A state of matter where molecules only move in place, not around each other.
Solid
How much molecules can move (vibrating in place vs. sliding Vs. flying away)
Freedom of movement
The phase change from a liquid to a gas
Evaporation
A state of balance between two opposing forces of processes
Equilibrium
The ”tug-of-war” between kinetic energy and molecular attraction.
Interaction
A state of matter where molecules move around, but not away from, each other
Liquid
The typical value of kinetic energy found by looking at all the molecules in a substance.
Average
The phase change from a gas to a liquid
Condensation
To become greater; happens to kinetic energy when energy is transferred to a substance
Increase
To break free; kinetic energy must do this to molecular attraction for a gas to form
Overcome
A state of matter where molecules can move away from each other entirely.
Gas
The process of moving energy into or out of a substance
Energy transfer
When a solid turns directly into a gas without becoming a liquid first
Sublimation
To become smaller; happens to kinetic energy when energy is transferred from a substance
Decrease
A specific type of matter; different ones have stronger or weaker attraction
Substance
