The pressure on a gas at -73˚C is doubled, but its volume is held constant. What will the final temp in ˚C

-Volume is constant so you can just ignore the variable.T2 = Variable youre looking for.P1 and P2 have no specific numbers but its double so you can use any numbers that make you happy as long as P2 is double of P1.Solve for T2 and youll get your answer in kelvin then just convert it back to Celsius by subtracting 273.-If you substitute different values for the initial and final volume, youll find that the temp.......

I know the P1V1/T1 = P2V2/T2
So even if you just help me with the values of each that would be great! I can take it from there..

Volume is constant so you can just ignore the variable.

T1 = Starting temperature in Kelvin (-73+273=200K)
T2 = Variable you're looking for.

P1 and P2 have no specific numbers but its double so you can use any numbers that make you happy as long as P2 is double of P1.

Solve for T2 and you'll get your answer in kelvin then just convert it back to Celsius by subtracting 273.

If you substitute different values for the initial and final volume, you'll find that the temp. remains the same

-75/2 = -75/2 or
-75/8 = -75/8 and so on
