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
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.

H20 is water.
1. Water in a solid form is ice. (when it is frozen)
2. Water in a gas form is steam, or water vapor. (when it evaporates)
3. Water in a liquid form is water. (not frozen, not evaporated)
4. A solid is a state of matter that has a fixed or definite shape in volume. (it cannot change its shape)
5. A liquid is a state of matter that has a fixed or definite shape in volume but takes the form of its container. (it can change shape, but is affected by gravity and will spread when given the option)
6. A gas is a state of matter that has no definite shape or volume. (it floats and is too spread out to contain or measure)
7. The particles of a gas have less attraction between them than the particles of the same substance in liquid or gas form. (gas particles are spread out farther, not having as much attraction to other particles)
9. Melting is a change in state of matter from a solid to a liquid. (like when water melts from ice to normal water)
10. Freezing is a change in state of matter from a liquid to a solid. (like when you make ice cubes out of putting water in the freezer)
12. Below the boiling point
13. Condensation is a change in state of matter from a gas to a liquid (like the water that forms drops on the pan lid when you boil water)
14. Sublimation is a change in state of matter from a solid to a gas (like when it's really cold outside, and the snow disappears from the roof without melting and causing puddles)
15. The freezing point of a substance is the same as the melting point of a substance.
16. The condensation point of a substance is the same as the dew point of a substance.
