A heat engine with 0.500 mol of a monatomic ideal gas initially fills a 1000 cm3 cylinder at 700 K . The gas goes through the following closed cycle: - Isothermal expansion to 6000 cm3. - Isochoric cooling to 400 K . - Isothermal compression to 1000 cm3. - Isochoric heating to 700 K .

2234.63

Explanation:

Work done per cycle by the engine is calculated as;

#Since volume doesn't change in the isochoric steps, there is no work done, hence:

#For an isothermal change of state(ideal gas):

#for the expansion process:

Hence, the engine does 2234.63J per second.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

your answer is, orbit around the nucleus
