Answer: 33.2\%

Explanation:

Given

83% heat is transferred and out of this, only 40% is converted to the mechanical energy of spinning turbine.

The overall efficiency is the product of all the efficiency i.e.

\eta_t=0.83\times 0.4\\\eta_t=0.332\ \text{or}\ 33.2\%

Oil spill can be very harmful to marine life because  the chemical make up of oils can be poisonous to marine life.
