The same amount of work (540 J) is done to compress the gas, this time in an isothermal process.
a. What is the change in internal energy of the gas?
b. How much energy is transferred by heat?
A steam engine absorbs 4.00 x 104 J and expels 3.20 x 104 J by heat.
a. How much work is done?
b. What is the efficiency of this engine?
c. If the engine exerts a constant force through a displacement of 25 m, how great is the force exerted by the engine?
The efficiency of a diesel engine is 0.35. The engine absorbs 2.00 x 104 J
by heat.
a. How much work does the engine do?
b. How much heat is expelled?
c. If this engine exerts a force of 175 N on an object, how far will the
object be displaced?
An experimental gasoline engine performs at 32 percent efficiency and
does 1.60 x 102 J of work in each cycle.
a. How much energy does the engine absorb by heat in a cycle?
b. How much energy is lost in each cycle?
c. How much work would the same engine do if it absorbed the same
amount of heat per cycle as described in a, but was operating at a 38 percent efficiency?
