Which of the following is NOT true when two systems with unequal temperatures come into contact with one another? O a. Heat will flow until thermal equilibrium is reached. O b. Entropy is reduced during the process. O c. The natural flow of heat will be from the warmer system to the colder system

6. An ideal gas expands isobarically from 3 atm from 400 to 600 ml. Heat then flows out of the gas at constant volume, and the pressure and temperature are allowed to decrease until the temperature reaches its original value. Calculate a) the total work done by the gas in the processes and b) the total heat flow to the gas.

SKIN temperatures (57 C)the iatent neat or vap moi water ny of watch p=998.2 kg/m'. 3. Assume that the thickness of the tissue between the interior and the exterior of the body is d =3 cm and that the average area through which conduction can occur is A =1.5 m². Find heat transferred by conduction per hour if temperature difference between the inner body and the skin is AT = 2°C. Coefficient of thermal for tissue without blood is K. = 18 × 10-2 Cal /m-hr-ºC.

If I bring a small object at temperature 200C in thermal contact with a large object at the same temperature, a) thermal energy will flow from the large to the small object because the large object has more internal energy. b) thermal energy will flow from the small to the large object because that will increase entropy. c) thermal energy will not flow.

Q1) There are four main thermodynamic processes that you learned from Unit 3: isobaric, isochoric, isothermal, and adiabatic. For each process below, classify it has one of these processes and then determine the signs of Q (the heat energy that flows into the gas), W (the work done by the gas), and AU (the change in internal energy of the gas). a) A container filled with an ideal gas has been submerged in a large water bath for a long time such that both reach thermal equilibrium. You then slowly compress the gas in the container. Assume the container is not well insulted so heat energy can easily flow back and forth between the water and gas and that the water bath is so large that its temperature does not change very much. b) A container filled with an ideal gas has a well-sealed piston that you put a pin in such that it doesn't move up or down. You then put the container over a burner to heat it up. c) A container filled with an ideal gas has a well-sealed piston that can move up or…
