One kilogram of ice at -5°c is mixed with 2 kg of water at 18°c in an insulated copper vessel of mass 1.5 kg. at equilibrium, the vessel contains both ice and water. determine the final mass of ice in the vessel. heat capacity of water =4.19 kj/kgk, heat capacity of ice= 2.04 kj/kgk, heat capacity of copper= 0.39 kj/kgk latent heat (fusion) =335 kj/kg

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?

Aheavily insulated piston-cylinder device contains 0.02 m3 of steam at 300 kpa and 200 °c. 1.2 mpa. d this process. team is now compressed in a reversible manner to a pressure of etermine the entropy change and the work done on the steam during this process
