AM+COMBINED+GAS+LAW

Combined Gas Law-Expresses the relationship between pressure, volume, and temperature of a fixed amount of gas.

Formula:**PV/T=k**

__** Sample Problem**__

If u have a helium gas in a balloon that has a volume of 50 mL with the pressure of 1 atm at 275 degree kelvin. What will the volume be with the pressure at 2 atm and the temperature at 273?

p1v1/t1=p2v2/t2 turns into v2=p1v1t2/t1p2

Plug in the numbers 50 mL x 1 atm x 273 K / 275 K x 2 atm = v2

__**v2 = 24.8 mL**__
