The volume of a balloon is 1 liter at 1 atm pressure and 0°C temperature.

Question

What volume is the ballooon at 2 atm pressure and 273°C temperature?

Answer 1

I hope you may have learned about the Ideal gas equation(PV=nRT), where P=Pressure of the gas , V=Volume of the gas , n=amount of gas/substance(in moles) , R= Universal gas constant , T= Absolute Temperature of the gas

We use this equation for the calculations regarding real gasses,assuming they are ideal gasses.

So in this case, n is a constant and the product of PV is directly propotional to T(as R is a constant).

So (PV)/T =nR(and it is a constant)

So simply substitute values for the left side of the equation, in these two cases and equate them to find the required volume.

Hope this helps.
