P1 =                                                    P2 =

T1   = T                                                T2 = T/2

V1   = V                                                V2 = 2V

   P1V1/T1    =    P2V2/T2

    P2           = P1V1T2/T1V2

                   = P1*V*T/2/T*2v

    P2              = P1/4

1.It is ¼ of its initial value

The ideal gas law PV=nRT relates pressure P, volume V, temperature T, and number of moles of a gas, n. The gas constant R equals 0.08206 L⋅atm/(K⋅mol) or 8.3145 J/(K⋅mol). The equation can be rearranged as follows to solve for n: n=PVRT This equation is useful when dealing with gaseous reactions because stoichiometric calculations involve mole ratios.
