120 kPa. Calculate the work done by the gas on the remains constant. The initial pressure of the gas is 250 energy is added in such a way that the quantity PV A gas is contained in a piston-cylinder arrangement, 5 energy is added in such a way that the quantity , kPa and the initial volume is 2 m'. If the final pressure in piston.

It is a Thermodynamics subject please show the complete and step by step solution. Use the given format I inserted. Please answer it as soon as possible.

Question 1b

Thermodynamics please. Clear writing and correct answer and steps. Thank you label all numbers on the p-v diagram process.

Draw and discuss the FBD for the following system. • Label all forces and directions. How many unknowns are there? (Remember, an unknown does not have to be a force. It can also be a dimension, angle, etc.) • How many equilibrium equations can you create? • Is there enough information to solve for the unknowns? Explain. ● Draw pulley A as your particle. B 20° A 100 N F

I need help on parts a and b, please. Part a is incorrect and I have no clue how to solve it correctly, please help. Thank you!

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

1. In general, the internal energy U depends on both temperature and volume, U=U(TV). The volume dependence comes from the potential energy due to the interactions among the particles. For free particles, there are no interactions, thus, the internal energy U should be independent of the volume, i.e., = 0. Verify this result for ideal gas pV = RT. au av
