Chapter 8, Problem 49ICA
The specific heats of aluminum and iron are 0.214 and 0.107 calories per gram degree Celsius [cal/(g °C)], respectively. If we add the same amount of energy to a cube of each material of the same mass and find that the temperature of the aluminum increases by 30 degrees Fahrenheit [°F], how much will the iron temperature increase in degrees Fahrenheit [°F]?

A motor has circular cylinders with a 3.875 inch diameter.
The height of the cylinder is 4.7 inches and has an ideal gas
The piston moves up in the cylinder and compresses the ideal gas. At the end of compression, the cylinder has a volume of 7.37 cubic inches
The amount of gas and the temperature of the gas stay the same during compression and the initial pressure in the cylinder is 1.2 atmosphere [atm].
Find the pressure after compression in units of pounds-force per square inch [psi].
An insulated, constant-volume system containing 1.36 kg of air receives 53 kJ of paddle work. The initial temperature is 27 C. Determine (a) the final temperature [1 decimal place] and (b) the change of internal energy [whole number].
1. Refrigerant R-22 with the mass of 2 kg is located inside the sealed container, initially saturated vapor at 6.8 bar. Heat was added to refrigerant and final pressure reached 20 bar according to pv=const. Neglecting the kinetic and potential energy changes determine:
Internal energy change in [J]
Heat added to the refrigerant in [J] and work done by fluid in [J].
3.draw the Temperature-volume diagram showing all stages.
4.What do you think about the final stage condition? Is it gas, liquid-gas, or liquid stage?
Use energy balance equation and find all unknowns using the NIST webbook.
