Homework Statement
This is for my physics homework and I haven't done gen chem in a while so I was wondering if this was right:
One mole of an ideal gas at 0◦C is held at a constant volume of 94 liter. Find the change in pressure if the temperature increases by 61◦C. Answer in units of atm.
Homework Equations
PV=nRT
The Attempt at a Solution
#1:
P1=?
V= 94 L
n= 1 mole
R= 0.0821 L atm / mol K
T1= 273.15 K
#2:
P2= ?
V= 94 L
n= 1 mole
R= 0.0821 L atm / mol K
T2= 334.15 K
Work:
#1:
P1 = [tex]\frac{nRT}{V}[/tex] = [tex]\frac{0.0821 x 1 x 273.15}{94}[/tex] = 0.238570372 atm
#2:
P2 = [tex]\frac{nRT}{V}[/tex] = [tex]\frac{0.0821 x 1 x 334.15}{94}[/tex] = 0.291848301 atm
change in pressure = P2-P1 = 0.291848301 - 0.238570372 = 0.053277659 atm
Is that right? TIA
