A600- g piece of metal is heated to 100°c and placed in an aluminum can of mass 400-g which contains 100-g of water at 17.3°c. the final equilibrium temperature of the mixture is 39.2°c, what is the specific heat of the metal?

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.
