Question

A sample of nitrogen at STP expands from 4.4 Liters to Standard Volume (which happens to be 22.4 Liters). If the Pressure was a constant 760 Torr throughout the expansion, the final temperature will = __ Kelvin

Answer 1

I think it's asking for you to use combined gas law.

STP = 273.15 K and 760 Torr/1 ATM

\[\frac{ P_1 V_1 }{ T_1 } = \frac{ P_2 V_2 }{ T_2 }\]
P1 = 760Torr
T1 = 273.15K
V1 = 4.4 leters

P2 = 760Torr
T2 = T2, you must find
V2 = 22.4 liters

Plug in and solve for T2
