1.	The efficiency of an ideal heat engine working between the freezing point and boiling point of water is ____
Answer» `12.5%` `26.8%` `6.25%` `20%` Solution :Freezing point of WATER `T_2=0^@C`=273 K Boiling point of water `T_1=100^@C` =373 K Efficiency `ETA=(T_1-T_2)/T_1xx100%` `=(373-273)/373xx100%` `=100/373xx100%` `=26.8%`
