A monatomic ideal gas (γ = 5/3) is contained within a perfectly insulated cylinder that is fitted with a movable piston. The initial pressure of the gas is 1.72 × 105 Pa. The piston is pushed so as to compress the gas, with the result that the Kelvin temperature doubles. What is the final pressure of the gas?
Homework Answers
Final pressure, Pf = Pi (Ti/Tf)Y/(1 - Y)
Pf = 1.72 x 10^5 x (Ti/2Ti)(5/3)/(1 - 5/3)
Pf = 1.72 x 10^5 x 22.5
Pf = 9.73 x 10^5 Pa

7.) One mole of an ideal gas is contained in an insulated piston-cylinder arrangement in an initial state T, P,V. The gas is allowed to expand adiabatically and irreversibly against a constant external pressure P. until a point is reached where the internal pressure becomes equal to Po. If C for the gas is constant and equal to 1.5 R, derive an expression giving the final temperature of the gas in terms of P., V, T, and R.

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...

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. (b) Is this thermodynamic process an isothermal expansion, an isobaric expansion or an adiabatic expansion? (c) Calculate the work done by the gas. (d) Calculate...

19.2----Six moles of an ideal gas are in a cylinder fitted at one end with a movable piston. The initial temperature of the gas is 26.3 ∘C and the pressure is constant. As part of a machine design project, calculate the final temperature of the gas after it has done 1730 J of work. Express your answer using three significant figures.
