    Charles' Law states: If the pressure of a gas sample is kept constant, the volume of the sample will vary directly with the temperature in Kelvin (Figure 9.9).

    this means T = k * V 320 = k * 40 k = 320/40 = 8 T = 8*V Can you solve it now?

    P1*V1=n*R*320K P2*V2=n*R*T2 P2=P1 and V2=20.0 or 1/2 of V1 so P2*V2= P1*1/2V1=1/2(P1*V1)=1/2( n*R*320K)= n*R*160K therefore 160K
