Water vapor initially at 3.0 MPa and 300ºC (state 1) is contained within a piston-cylinder device. The water is cooled at constant volume until its temperature reaches 200ºC (state 2). The water is then compressed isothermally to a state where the pressure is 2.5 MPa (state 3). Sketch this process on T-v and P-v diagrams and determine the specific volume at all three states and the quality at state 2.

Three point charges, two positive and one negative, each having a magnitude of 20 μc are placed at the vertices of an equilateral triangle (30 cm on a side). what is the magnitude of the electrostatic force on the negative charge

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg.how much energy e must be supplied to the device? express your answer in joules.
