Heat engines use heat to do work?
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.
Is it possible to construct a heat engine that produces no thermal pollution?
Atmospheric engines, or 'Stirling' engines, can make use of waste or naturally occuring heat differences, to work.
How does a heat engine differ from steam engine?
A heat engine is a broad term that encompasses any device that converts thermal energy into mechanical work, utilizing various heat sources and cycles. A steam engine, on the other hand, is a specific type of heat engine that primarily uses steam as its working fluid, typically generated by boiling water. While all steam engines are heat engines, not all heat engines are steam engines, as heat engines can also use gases or other fluids in their operation. The principles of operation may vary based on the type of working fluid and thermodynamic cycle employed.
Is 100 horsepower electric motor a heat engine?
No. electric motors aren't heat engines.
Why are heat engines important?
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.

What is caloric fluid theory?
The caloric fluid theory was a scientific hypothesis that suggested heat was a substance called "caloric" that flowed from hotter bodies to cooler bodies, explaining thermal phenomena. However, this theory was eventually replaced by the kinetic theory of heat, which proposed that heat is the motion of particles at the microscopic level.
If you occasionally stir water does it heat faster?
who knows fact not theory
Fact or theory is fire hot?
It is a fact that fire is hot. Fire produces heat through chemical reactions that release energy in the form of heat and light. This heat can cause burns and ignite other materials.

Why most heat produced by heat engines are tranffered to the environment?
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.

Is Mantle convection a fact or theory?
It is a fact im studying it and I know know this is a fact.
What is a good hypothesis for insects light vs heat?
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.
What is the greenhouse hypothesis?
The greenhouse hypothesis is the theory that increased levels of greenhouse gases, such as carbon dioxide and methane, in Earth's atmosphere are causing a warming effect on the planet. These gases trap heat from the sun, leading to global warming and climate change.
What is a hypothesis for which metal absorbs heat the most?
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!
