Embibe Experts Solutions for Chapter: Heat and Thermodynamics, Exercise 1: Exercise 1

A Carnot engine rejects heat at $27°\mathrm{C}.$ If it's efficiency is $25\%$ then it is taking heat from a source having temperature

If a Carnot engine works between $127°\mathrm{C}$ and $527°\mathrm{C},$ then its efficiency is

If the temperature of sink is at absolute zero, then the efficiency of Carnot engine will be

A Carnot engine whose sink is at $300 \mathrm{K}$ has an efficiency of $50\%.$ By how much should the temperature of source be increased so as the efficiency becomes $70\% ?$

A Carnot engine takes $6000 \mathrm{cal}$ of heat from a reservoir at $627°\mathrm{C}$ and gives it to a sink at $27°\mathrm{C}.$ The work done by the engine is

A Carnot cycle consists of

A Carnot engine is working in such a temperature of sink that its efficiency is maximum and never changes with any non-zero temperature of source. The temperature of sink will most likely to be

A heat engine rejects $600 \mathrm{cal}$ to the sink at $27°\mathrm{C}$. Amount of work done by the engine will be (Temperature of source is $227°\mathrm{C} \&\mathit{ }J=4.2 \mathrm{J} {\mathrm{cal}}^{-1})$
