A sample of n moles of a monatomic ideal gas is expanded isothermally and reversibly at a constant temperature T from a volume V to 3V. Note that since the temperature of the gas is constant, the internal energy will remain constant. a) Write an expression for the change in entropy ΔS for the system. b) The sample has 7 moles of gas and is kept at a temperature of 305 K. The volume is changed from 0.065 m3 to...
We start with 5.00 moles of an ideal monatomic gas with an initial temperature of 133 ∘C.

A 0.4 mol of a monatomic gas (dof = 3) is held inside a cylinder and piston as shown below. The gas is initial at a temperature of 293K. The air outside the piston and cylinder exerts an average force of 1313N. A flame is held to the cylinder and heat is added to the gas. The piston slides to the left a distance 0.08 m as 175 Joules of heat is added to the gas. What is the final...

A cylinder with a movable piston contains 17.5 moles of a monatomic ideal gas at a pressure of 1.66 × 105 Pa. The gas is initially at a temperature of 300 K. An electric heater adds 46600 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 CPCP = 20.79 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is...
400 moles of an ideal monatomic gas are kept in a cylinder fitted with a light frictionless piston. The gas is maintained at the atmospheric pressure. Heat is added to the gas. The gas consequently expands slowly from an initial volume of 10 m3 to 15 m3. (a) Draw a P-V diagram for this process.
