A cylinder of volume 0.300 m3 contains 10.0 mol of neon gas at 20.0?. Assume neon behaves as an ideal gas.
(a) What is the pressure of the gas?
(b) Find the internal energy of the gas.
(c) Suppose the gas expands at constant pressure to a volume of 1.000 m3. How much work is done on the gas?
(d) What is the temperature of the gas at the new volume?
(e) Find the internal energy of the gas when its volume is 1.000 m3.
(f) Compute the change in the internal energy during the expansion.
(g) Compute ?U - W. (h) Must thermal energy be transferred to the gas during the constant pressure expansion or be taken away? (i) Compute Q, the thermal energy transfer. (j) What symbolic relationship between Q, ?U, and W is suggested by the values obtained?
