A gas has a volume of 4.25 m3 at a temperature of 95.0°C and a pressure of 1.05 atm. What temperature will the gas have at a pressure of 1.58 atm and a volume of 2.46 m3?

Question

A. 356°C
B. 82.7°C
C. 47.5°C
D. 321°C

Answer 1

You know PV=kT

That means that PV/T = k is constant

So, you want T (in °C) such that

1.58*2.46/(T+273.15) = 1.05*4.25/(95.0+273.15)

T = 47.5°C
