Which equation converts from oC to K?
K=oC + 298
K=oC + 273
K=oC - 273
you need to use a conversion table for this
Which equation do you use? "A balloon with a volume of 2L at 25oC is heated to 300oC. What is the new volume?"
P1V1=P2V2
P1 / T1=P2 / T2
V1 / T1=V2 / T2
PV=nRT

P1V1=P2V2
P1 / T1=P2 / T2
V1 / T1=V2 / T2
PV=nRT
Which equation do you use? "A 4L container at 298K contains 0.5 moles of gas. What pressure is the container?"
P1V1=P2V2
P1 / T1=P2 / T2
V1 / T1=V2 / T2
PV=nRT
