[Solved] The efficiency of an ideal heat engine working between the f

Concept - • The temperature at which water changes its state from liquid to ice is called freezing point of water. • The freezing point of water is 0 °C. • The temperature at which water changes its state from liquid to vapor is called boiling point of water. • The boiling point of water is 100 °C. Carnot engine: • The ideal heat engine which works on Carnot cycle is called as a Carnot engine. • It gives the maximum possible efficiency among all types of heat engine. The efficiency (η) of a Carnot engine/ideal heat engine is given by: \(\eta =1-\frac=1-0.732=0.268\) Efficiency (η) = 0.268 × 100 % = 26.8 % Important points- • The temperature in the formula of efficiency should be in Kelvin scale always. The relation between °C and Kelvin (K) is given by: K = C + 273
