Question
Part A and B are fine, I just cannot get part C.
One mole of ammonia gas is contained in a vessel which is capable of changing its volume (a compartment sealed by a piston, for example). The total energy U (n Joules) of the ammonia is a function of the volume V (in cubic meters) of the container, and the temperature T (in degrees Kelvin of the gas. The differential du is given by Du=840Dv+27.32Dt. How does the energy change if the volume is held constant and the temperature is decreased slightly? A. it decreases slightly it increases slightly? it does not change How does the energy change if the temperature is held constant and the volume is increased slightly? it increases slightly B. it decreases slightly it does not change Find the approximate change in energy if the gas is compressed by 150 cubic Centimeters and heated by 5 degrees Kelvin. Change is energy= phi case include units in your answer.Explanation / Answer
A) as when volume is held constant ; hence energy is proportional to temperture. therefore as temperature decreases, energy decrases.
option A is correct
as when temerature is held constant ; hence energy is proportional to volume.therefore as volume increases, energy increases.
option A is correct
change in energy =840*150*10-6+5*27.32 =136.726
