the @nd law of thermo prhibits it.

The efficiency of an ideal ( carnot engine ) = 1 - ( T₂ / T₁ )

where T₂ = temp of the sink

and T₁ = temp of the source

now since T₂ can never be 0 ( abs zero is not possivle to achieve ) , he efficiency of an ideal ( carnot engine ) can never be 1 ( i, e, 100% )

NO BECAUSE SOME HEAT ENERGY IS CONVERTED IN2 SM ODR ENERGY ACCORDNG 2 2ND LAW OF THERMODYNAMICS..SO we CNT CONVERT THE HEAT ENERGY IN2 100% USEFUL WORK..........HOPE DS HELP U FRN
