buoyant force
The process of changing from a gas to a liquid.
condensation
Mass of an object divided by its volume.
density

freezing
Matter that does not have a definite shape or volume; has particles that move at high speeds in all directions.

melting
States that when a force is applied to a confined fluid, an increase in pressure is transmitted equally to all parts of the fluid.
