Question 390: Thermodynamics & KTG

Question

A Carnot's engine working between 400 K and 800 K has a work output of 1200 J per cycle. The amount of heat energy supplied to the engine from the source in each cycle is :

Accepted Answer

$$\eta  = 1 - {1 \over 2}$$
$$\eta  = {1 \over 2}$$
$${W \over Q} = \eta $$
$${{1200} \over Q} = {1 \over 2}$$
$$Q = 2400J$$

Answer

2400 J

Answer

1600 J

Answer

1800 J
