What is a proposed explanation made on the basis of limited evidence as a starting point for further investigation?

Hypothesis

200

The smallest unit of a substance that retains its chemical identity and properties, consisting of two or more atoms held together by chemical bonds.

Molecule

200

The process where a substance transforms from a solid state to a liquid state due to an increase in its internal energy, typically from absorbing heat.

Liquid to Solid

400

The ability of a system, whether physical, biological, or abstract, to move or change its state without significant restrictions or constraints.

Freedom of Movement

400

The direct conversion of a substance from a solid to a gas without passing through the liquid phase, seen in examples like dry ice.
