Question

The volume of a fixed mass of gas at300k is 10L what Will be the volume of the gas if the temaprutre is doubled without changing the pressure

Answer 1

Answer:

We can use the Ideal Gas Equation to solve this question: PV = nRT

• P is pressure in Pa

• Vis volume in m ^ 3

•nis number of moles of gas

• R is the universal gas constant, 31J / K mol

• T is temperature in KelvinIn your scenario, when mass is fixed, the number ofmoles will be fixed, too. So we can combine bothconstant terms n and R to give us: PV = kT where k is a constant.Now, since we want to work out how volume changes,let's put V on the left-hand side and move P to the right-hand side: V = (kT)/P So from the equation, we can deduce that whentemperature and pressure are both doubled, the VolumeV will remain unchanged as the numerator term T andthe denominator term P are both affected by a multipleof 2, hence can be cancelled away: V= kT(*2) P(*2) = kT P

Hope this helps!
