Part A At extremely low temperatures, the specific heats of metals are proportional to the absolute temperature T. For example, the specific heat of copper is c = (0.011 J/kg K)T for temperatures below What is the entropy change of 850 g of copper as it is heated from 0.5 K to 2.0 K? 2 K.

Problem 2 One mole of an ideal gas initially at 298 K and 100 k Pa is isothermally, reversibly compressed from 100 k Pa to 1000 k Pa. The internal energy U of an ideal gas only depends on temperature T and is independent of pressure p. For the process, please calculate the amount of each following quantity: a. Change in the internal energy of the ideal gas Au. b. Entropy produced A sir. c. Work done by the surrounding on the one mole of ideal gas. d. Heat transfer from the one mole of ideal gas to the surrounding. e. Entropy exchanged As between the one mole of ideal gas and the surrounding. f. Change in the molar entropy As of the one mole of ideal gas. g. Total entropy change A S,ot of the one mole of ideal gas plus the surrounding. h. Change in the mechanical energy of the one mole of ideal gas A Uy = – A (pv). i. Change in the thermal energy of the one mole of ideal gas Aur = A (Ts). j. Change in the chemical energy of the one mole of ideal gas Auc = Aµ. k. Change in the enthalpy…

Your calculator can't handle enormous exponents, but we can make sense of large powers of e by converting them to large powers of 10. If we write e = 10°, then eß = (10ª)³ = 108.
