Question

A Carnot engine working between and 600K has work output of 800 J per cycle. What is amount of heat energy supplied to the engine from source per cycle

• A. 1800 J/cycle
• B. 1000 J/cycle
• C. 2000 J/cycle
• D. 1600 J/cycle

Answer 1

Answer: (D)

1600 J/cycle

Answer 2

$Q = \left( \frac { T _ { 1 } } { T _ { 1 } - T _ { 2 } } \right) W$

$= \frac { 600 } { ( 600 - 300 ) } \times 800$=1600 J
