MY NOTES
A cylinder of volume 0.320 m³ contains 10.4 mol of neon gas at 18.8°C. Assume neon behaves as an ideal gas.
(a) What is the pressure of the gas?
Pa
(b) Find the internal energy of the gas. For a monoatomic ideal gas, the internal energy is U = 3nRT/2.
(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?
K
(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 $\Delta U - W$.
(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, $\Delta U$, and W is suggested by the values obtained?
