Question

Calculate the final pressure, in atmospheres, for each of the following with n and V constant.


A gas with an initial pressure of 1.20 atm at 82∘C is cooled to -28∘C.

The easy way to do this is to remember the gas laws. Pressure increases with increasing temperature. Therefore, if T is going from 82C to -28C you know it is being cooled which means the pressure will decrease. So make the factor so you get a smaller number. Remember T must be in kelvin.

Final P = 1.20 atm x (T factor)
