O When water freezes its entropy decreases. O The coefficient of performance for a heat pump is the ratio of the energy delivered at the higher temperature to the work put into the system. O The coefficient of performance for a refrigerator is the ratio of the energy removed at the lower temperature to the work put into the system. O The total entropy of a closed system is always increasing is one way of stating the second law of thermodynamics.

Octane is heated in a heat exchanger under constant pressure of 10 bar from 200 K to 400 K. Use the SRK equation to calculate the heat added to the system. Report your answer in units of kJ/mol using three decimal places. The ideal gas heat capacity of octane may be assumed constant and CPig/R=23.174. Under these conditions octane is a liquid.

Problem 2: The enthalpy of a system is given by the equation H = U + PV where U is the internal energy, P = pressure, and V = volume. In addition, the internal energy, U = Q + W where Q is the heat and W is the work. Suppose we want to find the rate of change in the enthalpy at constant pressure of 1.25 atm, what is the value when heat is absorbed by the system at a rate of 45 J/s and work is done by the system at a rate of 100 J/s when the change of volume is rated at 35 x 105 m/s? 1. What is the change in heat with respect to time? 2. What is the change in internal energy of the system with respect to time? 3. What is the change in enthalpy of the system with respect to time?
3.2. Heat and Work 0.2 kg of argon (mon-atomic ideal gas, R = 0.208 kJ/kgK ), initially at 250K, are confined in an isochoric system of 0.15 m^3 volume, and 2.5 kg of xenon (mon-atomic ideal gas, R = 0.063 kJ/kgK ), initially at 420K, are confined in an isobaric piston-cylinder system at 1.8 bar. Both systems are brought into thermal contact and equilibrate their temperatures with no heat loss to the outside. What is the final temperatures, pressures and volumes of both gases, the work done by both systems, and the amount of heat transferred between the two systems and the total generation of entropy? (Sgen= ∫ Sgen dt ) and s=Cv =3/2R, Cp =5/2R
This is not a graded question so please don't disregard it as if it is. Thank you in advance professor!
i. Draw a P-V graph to represent the changes undergone by the air ii. Calculate the maximum volume of the air. iii. What is the maximum pressure of the air? iv. State how the net work done on the air for the whole process can bedetermined.
In the engine of a car that uses petrol as fuel, when the piston is at its highest position, air at 10 bar and 100°C enters the cylinder. Without any change in the volume, ignition occurs, and the air temperature rises to 1500°C. What is the air pressure after the ignition? (Select the closest value)[Whenever necessary, assume air as an ideal gas and consider R = 287 J/(kg.K).]
