Statement-I: It is impossible to derive continuous supply of work by cooling a body to a temperature lower than that of the coldest of its surroundings
Statement-II: Heat engine can convert whole of the heat energy supplied to it into useful work
Statement-II: Heat engine can convert whole of the heat energy supplied to it into useful work
View answer and explanation
Correct option: B
Statement-I is true and statement-II is false
Option B (Statement-I is true and statement-II is false) is correct because the second law of thermodynamics prevents cooling a body below its surroundings and complete heat conversion to work.
