Answer 2

Answer:

A Carnot engine is an ideal heat engine that works between two heat accumulators at different temperatures and has the highest possible efficiency.

It works in a reversible cycle where at high temperature it absorbs heat from the source, works and at low temperature gives off heat to the receiver.

Explanation:

In this problem, the Carnot engine operates between an ice point and a vapor point, which are treated as two heat accumulators. The ice point temperature is 0°C and the vapor point temperature is 100°C.

Since the engine receives 746 calories of heat from the source each cycle, we can use Carnot's efficiency formula to calculate how much heat it is dumping back into the canister:

Efficiency = (T1 - T2) / T1

where T1 is the source temperature and T2 is the sink temperature.Replacing the values ​​we get:

Efficiency = (100 - 0) / 100 = 1

Since the efficiency is 1, all the heat absorbed by the engine is converted to work and no heat is lost to the absorber.
