How does friction play a role in the conservation of energy from one form to another?
In many energy conversions, some energy gets lost - in some cases through friction. Of course, according to the Law of Conservation of Energy, energy can't really diseappear, but it does get converted into low-value forms, i.e., unusable energy.
What kind of energy is lost energy?
Lost energy is typically converted into heat energy, which is a less useful form of energy as it cannot be easily converted back into a more usable form. This often occurs due to inefficiencies in energy conversion processes, such as friction or resistance in mechanical systems.
Describe how the energy changes from a usable form to a less usable form in a building's heating system?
While producing heat energy is precisely the purpose of a heating system, once any kind of energy is converted into heat, it can no longer be converted back to other forms of energy - at least, not all of it.
What is dissapated energy?
Dissipated energy is the energy that is lost or converted into a less useful form in a system, usually in the form of heat. It occurs when energy is transformed from one form to another and is no longer available to do work. Examples of dissipated energy include frictional forces, air resistance, and electrical resistance in a circuit.
Why can you never get as much usable energy out of a generator as you put into it?
In a generator, some energy is lost as heat due to friction in moving parts, electrical resistance in wires, and inefficiencies in the conversion process from mechanical to electrical energy. These losses lead to a decrease in the overall efficiency of the generator, meaning that the usable energy output is always less than the input energy. This principle is described by the second law of thermodynamics, which states that energy cannot be created or destroyed, only transformed from one form to another with some energy being lost as heat in the process.
Whenever energy is transformed there is always an increase in?
Entropy, according to the second law of thermodynamics. This increase in entropy represents the dissipation of energy into a less usable form during energy transformations.
Is there an instance when energy is used without being transformed?
No. "Using" the energy means changing it from one form to a less valuable form.

Can energy go from more usable forms to less usable forms?
No, never heard of such a comparison.Entropy is a measure of how much of the energy of a system is available *) to do work and how much of it is manifest *) as heat.*) Maybe one could say: potentiallyavailable and potentially manifest , but that is not the same as potential energy.Clausius defined the change in entropydS of a thermodynamic system, during a reversible process, asdS = δQ / TwhereδQ is a small amount of heat introduced reversibly to the system,T is a constant absolute temperature

Friction doesn't convert energy if actually destroys it true or false?
True. Friction converts mechanical energy into thermal energy, causing a loss of energy in the form of heat. It does not actually destroy energy, but it makes the system less efficient by dissipating energy in the form of heat.
Why is the mass of reactants less than the product in nuclear fission?
A part of mass is transformed in energy.
What does it mean to use up 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
