- One mole of gas expands isothermically to double its volume. If the gas temperature is 340 K, what energy is absorbed? (Round your answer to the nearest whole number.)Is the statement true of false? Support the answer a. For every cyclic process, the final state of the surroundings is the same as the initial state of the surroundings.Calculate the final pressure of a sample of water vapour that expands reversibly and adiabatically from 97.3 Torr and 400 cm3 to a final volume of 5.0 dm3. Take γ = 1.3.
- Calculate the value of CP at 298 K and 1 atm pressure predicted for CH4(g) and C2H4(g) by the classical equipartition theorem. Compare the predicted results with the experimental results and calculate the percent of the measured value that arises from vibrational motions. Repeat the calculations at 800 K and 1 atm using the relation below: Cp,mIs this statement true?Calculate the value of cP at 298 K and 1 atm pressurepredicted for CH4(g) and C2H4(g) by the classical equipartition theorem. Compare the predicted results with the experimental results (see Appendix D) and calculate the percent of the measured value that arises from vibrationalmotions.
