Heat is far from useless energy. Without this energy force you would die. Furthermore, without the heat internal combustion motors would never work. No Heat=Pluto.
Heat is not listed as a "form" of energy. Heat is the transfer of energy from a warmer body or region to a cooler one. As for internal combustion engines heat is a by product when they r turning chemical energy into kinetic energy. Also car engines are about 25% efficient when you look at output energy over input energy. You lose 75% to friction, sound, heat, etc..

How much energy is wasted for every 1000 megajoule?
It depends on the efficiency of the appliance. If an electric motor has an efficiency of 0.7, then for every 1000 megajoules, 30 megajoules will be wasted as useless heat or sound or other useless energy form.
Which sequence of energy transformations occurs after a battery-operated flashlight is turned on?
Chemical energy from the battery gets converted to electricity; in the light-bulb, assuming the old-fashioned incandescent light-bulbs, the electricity gets converted to heat, and the heat gets converted to light (part of it; a significant part gets converted to useless heat).Chemical energy from the battery gets converted to electricity; in the light-bulb, assuming the old-fashioned incandescent light-bulbs, the electricity gets converted to heat, and the heat gets converted to light (part of it; a significant part gets converted to useless heat).Chemical energy from the battery gets converted to electricity; in the light-bulb, assuming the old-fashioned incandescent light-bulbs, the electricity gets converted to heat, and the heat gets converted to light (part of it; a significant part gets converted to useless heat).Chemical energy from the battery gets converted to electricity; in the light-bulb, assuming the old-fashioned incandescent light-bulbs, the electricity gets converted to heat, and the heat gets converted to light (part of it; a significant part gets converted to useless heat).
How does the second law of thermodynamics relate to how energy is passed on through the food chain?
The second law of thermodynamics states that as more chemical reactions occur, more heat energy is released in to the atmosphere. Apparently, heat energy is useless and so as more energy is transformed into heat energy, more entropy (or instability in the overall universe) becomes prevalent. So as energy is being consumed and passed up the food chain, chemical reactions to digest the food occurs and , as a result, entropy increases.
What is the movement of energy from warmer object to a cooler object?
the movement of energy from a warmer object to a cooler object is called heat transfer
Are energy and heat synonymous concepts?
Heat is a form of energy. Therefore they are not synonymous as whilst all heat is energy, not all energy is heat.

Why doesn't the principle of mechanical energy conservation hold in situations when frictional forces are present?
In the case of friction, energy is wasted, i.e., mechanical energy is converted into useless energy, mainly heat.

Why is the transfer of energy in an ecosystem referred to as energy flow not energy cycling?
Entropy. To "cycle" the energy would need to be reused, in reality the energy flows in from the outside and flows back out. (If the system were energy blocked, then all the energy would convert to heat and thus be useless.)
How can enzymes be made useless?
large amounts of heat can denature enzymes and render them useless
Is Potassium Salt a source of non-conventional energy?
Potassium is a chemical element with symbol K (from Neo-Latin kalium) and atomic number 19. Elemental potassium is a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive with water, generating sufficient heat to ignite the hydrogen emitted in the reaction. since the potassium will be converted into a useless form of energy which is the heat energy that will be released to the surroundings and will become a oneceaagain as what i have said a useless form of energy.
A condition in which the heat is uncoordinated and useless as a pump?
Fibrillation
How can energy be lost from a food web?
Total energy is always constant; however, on the other hand, it is possible to convert useful energy into useless energy. This is an irreversible process, so for all practical purposes, this energy is "lost". It still exists as some type of energy (usually heat), but it can no longer be used.
Electric bulb gets very hot as compared to energy saver.why is it so?
A normal lightbulb wastes a lot of energy. What this really means is that electrical energy gets converted to heat. For most purposes, this can be considered useless energy - although in a few applications, this is actually desired.

Is the amount of disorder or useless energy in a system?
Entropy
