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. ( 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)

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...

1/2 Question 3 A piston-cylinder assembly fitted with a paddle wheel contains air, initially at 38°C, 125 kPa, and a volume of 0.02 mº. Energy in the amount of 1.8 kJ is transferred to the air by the paddle wheel. The volume of the air in the piston-cylinder increases to 0.05 mº at constant pressure. If the heat transfer between the air and its surroundings can be ignored, determine (a) the mass of the air in the piston-cylinder (b) the...

(THERMODYNAMICS) A vertical cylinder fitted with a frictionless piston contains 1.5 kg of H2O initially at 100 °C, 400 kPa. If the volume of the system reaches 0.5 m3, the piston hits a set of stops and is restrained from further upward travel. The system is heated to 200 °C. (Use saturated water tables, steam tables, and superheated tables as necessary) a) If the piston reaches the stops, determine the temperature and pressure when the piston first touches but exerts no force...

A cylinder fitted with piston contains 0.2 kg of N2 at 100 kPa and 30°C. The piston is moved compressing N2 until the pressure becomes 1 MPa and temperature becomes 150°C. The work done during the process is 20 kJ. Determine the heat transferred from N2 to the surroundings. Take Cv = 0.75 kJ/kg K for N2.

A piston–cylinder assembly fitted with a slowly rotating paddle
wheel contains 0.19 kg of air, initially at 300 K. The air
undergoes a constant-pressure process to a final temperature of 420
K. During the process, energy is gradually transferred to the air
by heat transfer in the amount 12 kJ.
Assuming the ideal gas model with k = 1.4 and negligible
changes in kinetic and potential energy for the air, determine the
work done by the paddle wheel on the...

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
