ASAP One piston of a hydraulic lift holds 1.40x10^3 kg. The other holds an ice block that is 0.076 m thick. Find the first piston's area.

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.
