chemistry help...?

Question

what a harsh day in chemistry class..
omg there is a test comin soon
can anyone help me define /expain and observed behavior of gases.

Boyle's law
charles' law
combined gas law
dalton's law of partial pressures
diffusion
effusion
gay-lussac law
ideal gas constant
ideal gas law
partial pressure

i'm will be glad if you can help me on my test...

Answer 1

As Pressure goes up, volume goes down, and vice versa. As Temperature goes up, Volume goes up, and vice versa. As temp. goes up, pressure goes up, and vice versa. What you do is use the starting "known" information and determine what you need to multiply by. If you need a bigger answer, make the info an improper fraction (Ex. 6/2). If the new V,P,or T goes down, you need a proper fraction(ex. 3/5). You get the fraction by comparing the new information to the old info.

Hope this helps

Answer 2

This is an entire chapter you want covered in a paragraph or two.

Think of a balloon. When you squeeze it (higher pressure) the volume goes down. If you heat the balloon, the volume goes up. If you add more gas to the balloon, the volume gets bigger.

The key equation is PV = nRT. Everything else is derived from this.

Please go study. Good luck on your test.
