The thermodynamic energy of a monatomic ideal gas is temperature-independent, so that dU = 0 in an isothermal process (one in which the temperature does not change). Evaluate w_rev and q_rev for the isothermal reversible expansion of 1.000 mol of a monatomic ideal gas from a volume of 15.50 l to a volume of 24.40 l at a constant temperature of 298.15 K.
