What do we call solid H2O? What do we call gaseous H2O? What do we call liquid H2O? A _______ is a state of matter that has a fixed or definite shape and volume. A _______ is a state of matter that has a fixed or definite volume but takes the shape of its container. A ______ is a state of matter that has no definite shape or volume. The particles of a ____ have less attraction between them than the particles of the same substance in the solid or liquid state. When matter changes from one form to another we call it a ____________ change. Melting is a change in state of matter from a _______________ to a_______________. Freezing is a change in state of matter from a ______________ to a ______________. Liquid can change to a gas through two processes: evaporation - which happens at a temperature below the ______________ point, and vaporization - which happens at the substances boiling point. Condensation is a change in state of matter from ______________ to _______________. Sublimation is a change in state of matter directly from a ______________ to a _______________ without going through the liquid phase. The freezing point of a substance is the same temperature as the _________________ point of a substance. The condensation point of a substance is the same temperature as the _________________ point of a substance.

If you had two forces, one with a magnitude of 25 N and the the other with a magnitude of 100 N, what would be the maximum net force these forces could exert on an object?
