Avagadro's law

The last law we learned this week is Avagadro's law. This law states that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Charles's Law

The next law we learned was Charles's law. This law describes how gases tend to expand when heated. A modern statement of Charles's law is. When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly related. This is also a little easy to remember.

New Unit

We started a new unit this week and it is about gas laws. most of it is math so it isn't that difficult for me. Remembering the formulas might be a little tricky though so I hope I can get that down.
We have to know each law. the first one is Boyle s law. it just states the relationship between pressure and volume .
