chemistry pressure and volume

Question

If I have 17.0 liters of gas at a temperature of 67.0 °C and a pressure of 88.89 atm, what will be the pressure of the gas if I raise the temperature to 94.0 °C and decrease the volume to 12.0 L?

Answer 1

This is an application of the ideal gas law in the form of (P1V1)/T1 = (P2V2)/T2

Since you want to find P2... rearrange the equation to the form of (P1V1T2)/(T1V2) = P2

You need to convert your temperatures from Celcius to K by adding 273 to each.

P1 = 88.89 atm

V1 = 17L

T1 = 67 +273 = 340 K

V2 = 12 L

T2 = 94 + 273 = 367

P2 = ?

My rough estimate puts it at about 135 atm
