Problem 2
An ideal gas with moles is heated at constant pressure from absolute temperature to . Find heat supplied; molar heat capacity at constant pressure is . Assume ideal objects and components, neglect unstated losses, and use SI units. (a) Derive the primary requested quantity from the appropriate law. (b) Analyze quantitatively how the result depends on the given parameters. (c) Check a physically meaningful limiting case and explain its meaning. State sign conventions, show reasoning, and check dimensions. (a) Calculate the requested quantity from the data. (b) Give the law or expression showing parameter dependence. (c) Examine a limit consistent with the model. The gas receives heat Q and does work W; take work done by the gas as positive and use the gas constant Rg.
