Consider a system to be a certain mass of gas contained in a cylinder with movable piston as shown in the figure. The state of the gas and hence its internal energy can be changed by
(a) putting the cylinder in contact with the body at a higher temperature than gas
(b) pushing the piston down
(c) Either (a) or (b)
(d) Neither (a) nor (b)
