A fish at a pressure of 1.1 atm has its swim bladder inflated to an initial volume of 8.16 mL. If the fish starts swimming horizontally, its temperature increases from 20.0°C to 22.0°C as a result of the exertion. (a) Since the fish is still at the same pressure, how much work is done by the air in the swim bladder? (b) How much heat is gained by the air in the swim bladder? Assume air to be a diatomic gas. (c) If the fish stops and this quantity of heat is lost, by the fish to the water at 20.0°C, how much is the fish and the universe (fish + water) entropy variation?

You have a spherical heater, outside diameter = 3.40 cm, immersed in a container of water. In order to keep the water in the container heated to a constant temperature of 35.0°C you adjust the temperature of the spherical heater. You reach a steady-state condition when the surface temperature of the spherical heater is at 79.0°C. Assuming the electrical efficiency of the heater is 100.0%, calculate the power required by the heater (i.e., calculate q). Ignore radiation.
An ISOBARIC process is one in which the PRESSURE REMAINS CONSTANT. Answer the following questions regarding the isobaric process.
The first law of thermodynamics, ΔU = Q - W, when written as Q = W + ΔU, says that the heat into a system can be used to do work and/or increase the internal energy. Therefore, which process requires the most heat? Isobaric, isochoric, or adiabatic?
