Question # 1

Under what circumstances the efficiency of a Carnot engine will be 100%? Is it possible?

  • Ans 1: No, it is impossible.
    The efficiency of a Carnot engines will be 100% only when cold reservoir is at absolute zero temperature (ok).Such reservoirs are not available and hence the maximum efficiency is always less than one or 100%

Question # 1

A real heat engine is less efficient than cannot engine. Why?

  • Ans 1: Carnot engine operates in an ideal reversible cycle and ideal gas is used as the working substance.
    No practical heat engine can be perfectly reversible. All real heat engines are less efficient than carnot engine due to friction and other heat losses.

Question # 1

Why we reduce pressure in the tyre while moving on motorway?

  • Ans 1: We reduce the pressure in the tyre while moving on motorway because when a car is driven through some distance,its tyres become hot due to work done against friction between the tyres and the road which appears as heat. This heat is absorbed by the gas molecules contained in the tyre which results in an increase in pressure of the gas. If the pressure in the tyre is not reduced then the tyre may burst.
