Asample of argon gas has a volume of 5.40 l and a temperature of 15 °c. what is the final volume, in liters, of the gas if the temperature has been increased to 42 °c at constant pressure and amount of gas?

Based upon the ideal gas law: PV=nRT, we can derive the following for the effects of changes in temperature (K) on volume (L).
V1/T1 = V2/T2
V2 = T2V1/T1
V2 = (42)(5.4)/15 = 226.8/15 = 15.12
So the final volume will be 15.1 L, which makes sense because gases expand with increases in temperature.

Olá. porque a reação na temperatura é muito rapida a do copo : )
