A heat engine has the three step cycle shown above. Starting
from point A, 1.5 L (liter) of monatomic ideal gas expands in the
isobaric (constant pressure) process A to B at P = 2 atm. B to C is
isovolumetric process at V = 5 L, and C to A is an isothermal
(constant temperature) compression at 300 K.
1) Find the pressure (in atm) at
point C in atmospheres atm.
2) Find the heat (in J) exhausted in the process B
to C .
3) If the net work done by the engine per cycle is 342.2 J, find
the work done by the gas during process C to
A.
