Matter

1. is the every required to change a substance from solid to liquid at its melting point.
4. The substance or substances on which physical objects are made consists of, or rely on. Is anything that takes up space and has mass.
5. is the amount of heat needed to turn a liquid into vapor without a rise in the temperature of the liquid.
8. is a change in the state of water from a gas or vapor into liquid.
11. is the change of state from solid to a gas without passing through the liquid state.
13. Change of a sold into a liquid when heat is applied.
14. The state in which a substance's particles are more loosely packed
16. The process where water turns into a liquid into a gas.
17. is the rapid vaporization of a liquid when the liquid is heated to its boiling point.

2. Is a phase transition where a liquid turns into a solid when its temperature is lowered to its freezing point.
3. when gaseous substances condense into solid-state, without passing the liquid state.
6. is the conversion of liquids towards gases.
7. is the temperature at which liquids vapor pressure is equal to the external pressure acting on the surface of a liquid and making it... a gas.
9. Gasses do not have definite volume nor shape, they make gas spread to fill the container they are in.
10. The explanation of the behavior of particles depending on the state of matter.
12. is the temperature at which a solid melts.
15. is a state of matter which has its particles really close together.
