Question is: Find new pressure
if original is:
P:1.23 atm
V: 5.4 L
T:297 Kelv ( or 24 C)

and new is:
P: ?
V: 3.4 L
T: 361 or (58 C)

Gas Laws by Lussac, Charles and Boyles

Formula is
Combined: P1x V1/ T1 = P2xV2/ T2

Charles: V/T = V2/T2
Boyles: P1xV1 = P2xV2
Lusac: P/T = P2/T2

omg i love doing these!

P_2=(T_2*(P_1*V_1/T_1))/V_2

(P1*V1)/(T1) = (P2*V2)/(T2)

(1.23*5.4)/(297) = (x*3.4)/(361)

Algebra from there.

Well you're given the P, V, and T so you used the Combined Law. You have your P1 V1 and T1, your V2 and T2. You need to find P2 so just plug it in and solve for P2. Not that difficult. Make sure you use the same units for Temp.
