Why heat cannot be converted into work and why work can be converted into heat?

A lower order energy cannot be completely coverted into a higher order energy. Heat energy is a lower order energy and work is higher order energy. Therefore it is not possible to convert heat into work without loosing some energy according to the second law of thermodynamics. But a higher order energy can be coverted completely into lower order energy and it will not violate the second law of thermodynamics.

Thermal energy that is not converted into work by a heat engine is called?
waste heat
How much heat is generated by 1700 joules of work?
If all 1700 Joules of work get converted into heat, then, of course, you get 1700 Joules of heat.
What happens to the energy from fuel that is not used to perform work?
Most of it is converted to heat, but the remainder is wasted.
If the work output of a machine is always less then the work input where does the missing work go?
The energy, lost to friction, is converted to heat and sound.
Is solar powered by heat or light?
The energy of the sun is converted in light, which is then converted in heat. After that, the heat converts into electrical.

What is the effect of heat of fats?
The most common effect of heat on fats is that it causes them to break down. They will become liquid but cannot be converted into gas even on excessive heat.
What kind of energy is coverted when you burn gasoline?
Chemical energy is converted into heat energy.Chemical energy is converted into heat energy.Chemical energy is converted into heat energy.Chemical energy is converted into heat energy.
Does the work energy theorem hold if friction acts on an object?
Yes, some work is converted into heat due to the friction.

What does it mean to use energy?
Using up energy is basically converting energy from its original form to such a form in which it becomes useless or it is converted to less usable form. FOR EXAMPLE - When you use electricity to light a bulb. electrical energy is converted to heat energy which is in turn converted to light energy. Now you cannot get back heat energy from that light and hence you cannot get back electrical energy. So here electrical energy is converted to such a form in which is cannot be used further. It is said to be used

How much energy released during muscle contraction is actually converted to useful work?
Only 40% of energy is converted to useful work. The rest is given off as heat to maintain homeostasis
