148606 The temperature of source of a Carnot engine of efficiency $20 \%$ when the heat exhausted is at $240 \mathrm{~K}$ is

148607 A refrigerator is to maintain eatables kept inside at 9 degree Celsius. If the room temperature is $\mathbf{3 6}$ degree Celsius, then what is the coefficient of performance?

148608 A heat engine absorbs $360 \mathrm{~J}$ of energy by heat and performs $25 \mathrm{~J}$ of work in each cycle. The energy expelled to the cold reservoir in each cycle is

148609 Consider an engine that absorbs 130 cal of heat from a hot reservoir and delivers 30 cal heat to a cold reservoir in each cycle. The engine also consumes $2 \mathrm{~J}$ energy in each cycle to overcome friction. If the engine works at 90 cycles per minute, what will be the maximum power delivered to the load? [Assume the thermal equivalent of heat is $4.2 \mathrm{~J} / \mathrm{cal}]$

148610 A Carnot's engine has an efficiency of $50 \%$ at sink temperature $50^{\circ} \mathrm{C}$. Calculate the temperature of source.
