Question

A gas occupies a volume of 31.0L at 17.0⁰C. If the gas temperature rises to 34.0⁰C at constant pressure, would you expect the volume to double to 2.0L?

Answer 1

V₀ – initial volume = 31 L

V – final volume = ? ml

T₀ – initial temperature = 17°C = 290 K

T – final temperature = 34°C = 307 K

Charles's law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant:

$\cfrac {V}{V_0} = \cfrac {T}{T_0}$

$V= \cfrac {V_0*T}{T_0}= \cfrac {31*307}{290}=32,8l$

Answer: 32,8 liters
