Heat energy is made when there is friction why is this useful?
This is useful because we can conduct heat and use it for human use
Why is conduction useful?
Conduction is useful because it allows you to heat solids. FACT: Solids heat faster than liquids and gases.

Can scientists construct an engine that does nothing but convert heat to useful work?
Yes - with certain limitations. You can convert part of the heat - not all of the heat - into useful work, if there is a heat difference. The remainder of the heat (from the hot container) gets passed to the cold container. You CANNOT convert ALL the heat into useful work, nor can you convert heat into useful work if there is no heat difference. All this would contradict the Second Law of Thermodynamics, and it is very unlikely that this law will ever be violated.
