Yes.
What is freezing?
The change of state from liquid to a solid.
What is melting?
The change of state from a solid to a liquid
What is boiling?
The change of state from liquid to gas.
What is condensation?
The change of state from a gas to a liquid
What is sublimation?
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.
What is room temperature?
25 Celsius
What is diffusion?
The process by which particles in liquids or gases spread out from a region where there is higher concentration to an area where there is lower.
What is concentration?
The amount of a substance in a defined space
