(a) How much energy in Joules is available from 1 barrel of
oil?
(b) What is the economic cost of keeping a 1 kW electrical heater
turned on for 2 hours a day over one year?
(c) A steam power plant operates in a cycle with the boiler at T1 =
340◦C and the condenser at T2 = 25 C. Calculate the maximum
efficiency allowed by the Second Law of Thermodynamics.
(d) Express the world power consumption as a fraction of the solar
power incident on the surface of the earth.
