Why is it impossible to create a perpetual motion machine?
Energy will eventually be converted into heat and the
machine will burn up.
Some of the energy will always be lost in the conversion
and therefore it will eventually stop.
The friction that exists within machines will eventually
cause the levers to break.
It is not impossible; perpetual motion machines already
exist.
Done

It is impossible to create a perpetual motion machine because some of the energy will always be lost in the conversion  and therefore it will eventually stop.

Correct Answer : Option B

Explanation:

The perpetual motion machine is impossible machine as it is hypothetical working machine which would be in motion for an indefinite time in continuity of the motion. The continuity of motion for an indefinite time would mean that the working principle of the machine would never allow the dissipation of energy from the machine and all the machine would ultimately reserve all the energy and be converting it into forms without any loss.

This working principle is violation of first and second laws of thermodynamics and hence a machine will eventually lose some of its energy in every conversion of the working cycle and hence there will be a time where the machine would be stopped, and hence a perpetual motion machine cannot be made.

explanation:

specific heat is the amount of heat required to raise the temperature of a unit mass of a substance.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
