law of energy conservation and theory
Answers
Answer:
What is the Law of Conservation of Energy?
The law of conservation of energy states that energy can neither be created nor be destroyed. Although, it may be transformed from one form to another. If you take all forms of energy into account, the total energy of an isolated system always remains constant. All the forms of energy follow the law of conservation of energy. In brief, the law of conservation of energy states thatIn a closed system, i.e., a system that is isolated from its surroundings, the total energy of the system is conserved.So in an isolated system such as the universe, if there is a loss of energy in some part of it, there must be a gain of an equal amount of energy in some other part of the universe. Although this principle cannot be proved, there is no known example of a violation of the law of conservation of energy.
The amount of energy in any system is determined by the following equation:
Law of Conservation of Energy
UT is the total energy of a system
Ui is the initial energy of a system
Q is the heat added or removed from the system
W is the work done by or on the system
The change in the internal energy of the system is determined using the equation
Energy can neither be created nor be destroyed it can be changed from one form to another.
Heat energy changes into mechanical energy in vehicles produced due to combustion .
For any thing to happens or things to move or even change - for chocolate to melt or a rocket to fly we needs energy.
Energy is the capacity to do work, and by this they simply mean energy makes things happen. It come in many forms, from the chemical energy locked in sugar to the mechanical energy in a moving truck.
Energy conversion is when it changes from one form to another from the steam-powered turbines to electric power in power stations, for inśtañce.
