Properties of Matter
Non STP-use idel gas law.
They are easy to compress, they expand to fill their containers, and they occupy far more space than the liquids or solids from which they form.
Ex:V=volume of gas (L)
T=temperature (K)
n=amount (moles)
p=pressure (atmosphere).
The particles in real gas... Have their own volume, attract each other, gas behavior is at low pressure, high temperature in Non-Polar molecule, and they share equally.
Kelvin to Celsius-C=K-273.
