The volume of an ideal gas in a container is 2. 0 l. What will be the volume of the gas if the pressure on the container is doubled while the temperature is reduced from 400 k to 200 k?.

Can someone explain to me how to do this problem ?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
