A gas has a volume of 590 mL at a temperature of - 55°C what volume will the gas occupy at 30°C

Using ideal gas formula (PV=nRT), you can conclude that volume directly related to the temperature. That means an increase in temperature will cause an increased volume too. Note that the temperature is using Kelvin, not Celsius. The calculation would be:

V1/T1 = V2/T2

590ml / ( - 55 + 273) K = V2 / (30+273) K

V2 = (590ml / 218K) * 303K

V2 = 820ml
