An ideal gas contracts isothermally along a path from point 1 to point 2 as shown in the figure below 2 P1 0 V2 Vi If V1-10.2m2, V2-8.2m, T-241.9K, and n-47.8mols what is the final pressure p2? Answer in Pascals (Newtons per square meter)
An ideal gas is isochorically heated, moving from point 1 to point 2 according to the figure below. P2 P1 0 If the change in internal energy Δυ=517.11, initial pressure Pi=7616.9Pa, final pressure P-10860·7Pa, and n=55.0mols, how much energy Q is added to the system in the form of heat? Answer in Joules
A piston reversibly and adiabatically contracts 3.88 moles of ideal gas to one-tenth of its original volume, then expands back to the original conditions. It does this a total of five times. If the initial and final temperature of the gas is 27.5 degree C, calculate (a) the total work and (b) the total change in internal energy for the overall process.
In an engine, an almost ideal gas is compressed adiabatically (see Note below) to half its volume. In doing so, 2630 Joules of work is done on the gas. (a) How much heat flows into or out of the gas? (b) What is the change in internal energy of the gas? (c) Does its temperature rise or fall? Note: An adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. In...
