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 at constant n and T. [ Select ] ["A", "C", "D", "B"]

A quantity of neon gas is slowly heated in a cylinder fitted with a movable piston (constant pressure). It is known that 100.0 J of heat is added to the gas and the change in temperature is 4.00 K. How many moles of gas are contained in the cylinder?
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...

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...
