Steam flows through a pipe at the rate of 5kg/s. The pressure nd temperature are 12 bar nd 300 degree celsius respectively . If 2000J of heat is lost to the surrounding at constant pressure . Find the final condition of the steam.

A steel bar has a width of 10cm at 50°C. At what temperature will it fit exactly into a hole of constant width 10.005cm if coefficient of linear expansion of steel is 11*10^-6C-¹

A gas at pressure P1 N/m2 and temperature 30°C is heated to 61° C at constant volume. Find its new pressure

A system consists of a gas inside a cylinder. Inside the cylinder there is a 10 ohm resistor connected to an electrical circuit through which a current can pass. A mass of 0.1kg is placed on the piston which drops by 0.2 m and comes to rest. A current of 0.1 A is passed through the 10 ohm resistor for 2s. What is the change in the internal energy of the system when it has reached equilibrium?

An ideal refrigerator-a Carnot engine running backwards-freezes ice-cubes at a rate of 5gs-1 starting with water at its freezing point. Energy is given off to the room which is at 30°C. The fusion energy of ice is 320Jg-1. At what rate must electrical energy be supplied as work, and at what rate is energy given off to the room
