Question

A gas has a pressure of 713 mm Hg at a temperature of 24°C. What will the Kelvin temperature be if the pressure is increased to 3.71 atm?

Answer 1

We ASSUME constant volumes...and we convert temperatures to the absolute scale...

Explanation:

And so `P_1/T_1=P_2/T_2`...and we KNOW that `760*mm*Hg-=1*atm`...

And so...`T_2=P_2xxT_1/P_1`

`=3.71*atmxx(297.15*K)/((713*mm*Hg)/(760*mm*Hg*atm^-1))`

`=1175*K`...
