Answer 1

Ideal machine

1. In an ideal machine, all the input energy should be converted to output energy.
2. Conversion of energy is 100% in an ideal machine.
3. An ideal machine is that in which there is no dissipation of energy in any manner.

Efficiency

1. The efficiency of a machine indicates how well its input energy is converted to useful output energy or work.
2. In an ideal machine, all the input energy is converted to output energy.
3. Hence, the efficiency of an ideal machine is 100%.
