Heat engine are physical working machines, therefore they are fact
Yes. Heat engines come in various forms. For example, internal combustion using gasoline or diesel, external combustion (not much used), steam engines reciprocating or turbine, gas turbines, rocket engines.
Atmospheric engines, or 'Stirling' engines, can make use of waste or naturally occuring heat differences, to work.
No. electric motors aren't heat engines.
Heat engine is the gate way of transform thermal energy into another form of easy access energy. It allow us the refrigeration cycle and come the air condition, Popsicle and the refrigerator. It would take at least 3 times the electricity to heat up over winter compare to the transformation of electricity to heat by a heat engines. Our vehicle is operated base on heat engines principle and separated the medieval era with comfortness of modern society.

According to the theory of heat engines (read about "Carnot cycle" for more details), heat can not be converted 100% to other forms of energy. The remaining energy gets transferred from the "reservoir" of higher temperature, to the "reservoir" of lower temperature. The latter would be the environment. For example, if the heat engine works at 600 Kelvin, and the environment has a temperature of 300 Kelvin, in theory half the heat of the higher-temperature reservoir can be used. However, real engines have a lower efficiency than the theoretical maximum according to Carnot.

A hypothesis is a prediction on what you think will happen. For experiments on insects being attracted to light or heat, a hypothesis could be that insects are attracted to light over heat.
A hypothesis is a guess based on what you know. Which metal do YOU think will absorb heat the most? Write it as a statement and that will be your hypothesis: "I think _____ will absorb heat the most." It doesn't matter if your hypothesis is right or wrong, just that you have a guess.Of course, then you need to test your hypothesis and actually find out which metal does!
engines get discolored because of the heat . the heat comes from combustion from gass and air

Yes. Gasoline and diesel engines are both heat engines.
