2mol of an ideal gas at 25∘C is allowed to expand reversibly at constant temperature (isothermally) form a volume of 2L to 10L by reducing the pressure slowely. Calculate the work done by the gas (w),ΔU,q, and ΔH. View Solution 10mol of an ideal gas confined to a volume ...
What volume would be occupied at STP by 3.25 mol of an ideal gas? A gas has a volume of 1.75 l at -23.0^oC and 150.0 kpa. At what temperature would the gas occupy 1.30 l and 210.0 kpa? An ideal gas is allowed to expand fr...
A gas at a pressure of 2.5 atm undergoes a quasi-static isobaric expansion from 3.4 to 4.7 l. How much work is done by the gas? By what factor does the volume increase when an ideal gas is allowed to expand from 3.80 L to 32.3 L at constant temperature?

One mole of an ideal gas at 298 K is expanded reversibly and isothermally from 1.0 L to 10 L. Determine the amount of work in Joules. A sample of perfect gas containing a mass of 0.11 moles at 296 K is allowed...
There is no new physics in the principle of conservation of mechanical energy. Everything follows from Newton's laws (refer back to the introduction of kinetic energy and potential energy). It was natural to physicists to expand this idea by including every possible form of energy and to ...
The First Law can also be applied to an open system, where the boundaries of the defining control volume are such that not only energy can be exchanged across them, as is the case in a closed system, but also mass is allowed to flow into the system and/or out from it. Such a syste...
When the brakes are applied or the electric vehicle is decelerating, the motor transforms into an alternator and generates power, which is then returned to the battery. 2. Working Principles of HEV It has a fuel tank similar to a regular car that supplies gas to the engine. A set of batt...
