Re: Can heat be converted to kinetic energy (move a ball or turn turbines)???

Generally, yes.


But is Heat (Temperature wise) ever lost by being converted into
kinetic energy instead....meaning that if you have 100degrees of hot
liquid then this "TEMPERATURE" is never los (not converted)t?

Temperature is most definitely not "conserved" in any sense; nor is it
ever "converted" in any useful sense. Temperature is not, however, a
measure of the quantity of heat. Heat is simply energy, and the quantity
of heat in a given body is related to its total energy -- one adds heat
by putting energy into it, and one remove heat by removing thermal
energy. For most objects their temperature and the amount of heat they
contain are directly related, so relative temperatures can be used to
compare relative amounts of heat; when two objects are placed in thermal
contact, heat (energy) flows from the one with the larger temperature to
the one with lower temperature -- that's the basic meaning of
temperature: telling you which direction heat (energy) will flow.


For more than that you'll have to study some basic thermodynamics....


To answer the question in the subject: Yes. That's what a Stirling heat
engine does, as does the engine in your car (burning gasoline as a
source of heat). There are literally zillions of other examples....

Ok thanks Tom....I guess gazoline isn't hot and it generate huge heat
when a match is lit.

But as for a turbine ...like water I believe the heat (or heated
molecules) simply turns the turbine but is not absorbed or lost
(meaning not converted itslef into energy?)
