Phases of matter

Solid: Molecules are close together, but can move a little bit. Has a definite volume and shape and has an ordered molecular structure.

Liquid: Molecules are a bit farther away, allowing them to flow, but stay in the same general area. Takes the shape of it's container. Has a definite volume and a free shape, and has a semi-ordered molecular structure.

Gas: Molecules are farther away, and like liquid, takes the shape of it's container. most of the time invisible. Has a free shape and volume, and a random molecular structure.

Processes

Evaporation: When liquid heats up, the molecules move faster, making them eventually escape the liquid and turn into gas molecules.

Condensation: Gas molecules cool down and slow down, forming liquid. often happens on a cool surface in a warm environment.

Melting: When a solid heats up, the molecules speed up and flow, making the solid a liquid.

Freezing: When heat decreases, molecules in liquid slow down, making the liquid become a solid.

Sublimation: When molecules in a solid get moving so fast, sometimes a few escape and go into the air without going into a liquid.

Examples of How KTM relates to real life

Solid: Ice molecules are close together, but it's molecules can still move, so it needs to be kept cold to keep it a solid.

Liquid: Liquid water molecules are farther apart than solid molecules, so they can flow and take the shape of their container. however, they stay in the same general area.

Gas: water vapor molecules are farther apart than liquid water molecules, so they can spread apart to increase their volume to take up their container.

Melting: ice's molecules speed up when heated, allowing them to flow, turning ice to liquid water.

Evaporation: When liquid water is heated up, it's molecules speed up and escape the liquid, forming water vapor.

Condensation: When water vapor molecules slow down, they condense and become liquid water.

Freezing: When molecules in liquid water slow down, they become solid to form ice.

Sublimation: When ice is in a warm environment, it's molecules begin to move faster, and a few escape the ice to become water vapor.
