A heat engine operates with the cold reservoir at temperature 324K324K. The minimum temperature of the hot reservoir, if the heat engine takes 300J300J heat from the hot reservoir and delivers 180J180J heat to the cold reservoir per cycle, is _____ KK.
A heat engine operates with the cold reservoir at temperature 324K . The minimum temperature of the hot reservoir, if

Correct answer

0

Step-by-step solution

A heat engine operates with the cold reservoir at temperature 324K . The minimum temperature of the hot reservoir, if

Using the relation, Q2Q1=T2T1\dfrac{{Q}_{2}}{{Q}_{1}} = \dfrac{{T}_{2}}{{T}_{1}}

Or 180300=324T1⇒T1=324×300180=540K\dfrac{180}{300} = \dfrac{324}{{T}_{1}} ⇒ {T}_{1} = \dfrac{324 \times 300}{180} = 540K
