Ch. 3 Notes

Solids, Liquids, and Gases

What forms of matter are these?

Solids

Definite ___________________________ (crystalline)

Atoms _______________, but stay in same fixed positions (unless melting point is reached)

Liquids

Definite ___________________

No _______________________

Particles move randomly, but forces of attraction between atoms is less then in solids

Gases

No _________________________________

They take the shape of _________________________________________

Although there are forces of attraction among all particles, these _______________________ with gasses because the particles are moving so fast and are so far apart.

Kinetic Theory of Matter

All particles of matter are in __________________________

Absolute Zero= OK or -273 C, this is when the motion of all particles _____________________. It has never been reached.

Phase Changes

Phase change diagram

-During a phase change, energy may be added or taken away, but the temperature remains

__________________________

-Energy is being use to overcome the ___________________________.

Gas Laws

______________________- at a constant temperature, when the volume goes ____________ the pressure goes up, and vice versa

P1V1=P2V2

_______________________- at a constant pressure, as the temperature goes ________ the volume goes us and vice versa

V1/T1 = V2/T2

Temperature Scales

C= 5/9 x (F-32)

F=(9/5 x C) + 32

K= C + 273

C= K - 273
