An insulated cylinder fitted with a movable piston to maintain constant pressure initially contains 100 g of ice at -10 C. Heat is supplied to the contents at a constant rate by a 100 W heater. Make a graph showing temperature of the cylinder contents as a function of time starting at t = 0, when the temperature is -10 C and ending when the temperature is 110 C. Let c = 2.0 kJ/kg K for specific heat of ice from -10 to 0 C and of the steam from 100 to 110 C. The specific heat of water between 0 C and 100 C is c = 4.18 X 103 J/kg K. The value of Lv = 2257 X 103 J/ kg and Lf = 333.5 X 103 J/kg.

    Consider the following gaseous sample in a cylinder fitted with a movable piston. Initially there are n moles of the gas at temperature T, pressure P, and volume V. Choose the cylinder that correctly represents the gas after each of the following changes. Note 1: The degree of shading of the samples represents the gas concentration (i.e., darker red = more concentrated). Note 2: A figure/letter can be used more than once. A) The pressure on the piston is tripled...

    A cylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32 × 105 Pa. The gas is initially at a temperature of 300 K. An electric heater adds 43200 J of energy into the gas while the piston moves in such a way that the pressure remains constant. It may help you to recall that CP C P = 20.79 J/K/mole for a monatomic ideal gas, and that the number of gas...
