Please help with this problem:
a sample of gas at STP is to be heated at constant pressure until its volume triples. what is the new gas temperature?

You have to know the starting temperature, convert it to Kelvin, triple that and then convert back again.
Since you say STP, that implies 0C, which is 273K. So triple it!

Remember the relationships that exist between volume and temperature.
Its under my understanding that gas and temperature share a direct proportionality.

Your trying to find T2
V1 = 1
T1 = 1
V2 = 3
Solve for T2 and you get three. See its directly proportional.
I hope this is right..I haven't done chemistry in a while.

PV=nRT
given: P, n, R are constant
PV(1)=nRT(1)
P*3V(1) = nR T(2) => T(2) = 3* T(1)
The new temp is 3 times the starting temp.

546 degrees C.
