One mole of an ideal gas is confined to a container with a movable piston. The questions below refer to the processes shown on the PV diagram at right. Process I is a change from state Xto state Y at constant pressure. Process Il is a change from state W to state Z at a different constant pressure Rank the temperatures of states W, X, Y, and Z. If any temperatures are equal, state that explicitly. Explain. a. b. x...

The first law of thermodynamics is usually written as Q=W+?U. You need to look at the signs carefully; some other disciplines (chemistry, for example) may use other signs, which implies other definitions of these quantities. 1-Which physical law underlies the first law of thermodynamics? -conservation of matter -increase in entropy -conservation of energy -conservation of work 2- The quantity Q is the __________ that is added to the system. -heat - work -entropy -internal energy 3-The quantity W in the...

Cycles in a heat engine The basic idea of a heat engine is to
add heat to a gas, and have the gas perform work on its environment
via an expansion, which in turn is used to power motion. The gas is
then restored to its original temperature and the cycle begins
again. You can assume that the same amount of gas remains in the
engine during the cycle. A convenient way to think about these
cycles is a pressure...

A monatomic ideal gas undergoes isothermal expansion from 0.08 m3 to 0.22 m3 at a constant temperature (initial pressure is 310 kPa). What are its (a) internal energy change (ΔEΔE), (b) net heat transfer (Q), and (c) net work done (W)? Use negative quantity for heat transfer out of the system or work done on the system.
