Total amount of energy in any closed isolated system remains what?
If it is a closed system, the total energy remains equal.
As a result of friction between internal parts of an isolated system?
The total mechanical energy of the system remains the same.
Why doesn't the total mechanical energy in an isolated system change?
The total energy of an isolated system will not change if it has no interaction with the outside.The reason for this is that energy is conserved.(To be exact about it, one needs to be a little picky about what it means means to be isolated. That means no radiation of light and no gravitational interactions and no electromagnetic forces, but that is pretty much understood when one says "isolated.")Mechanical energy does not generally include things like heat, electromagnetic energy and chemical energy, to name a few.Assuming mechanical energy is entirely kinetic and potential energy, then energy is conserved in an isolated system only if the exchange of energy is between mechanical and potential. Expand the definition of "mechanical energy" and you can exchange between any forms of energy in your definiion.That is the only condition that the conservation of mechanical energy is achieved.
What is true about the total energy in a system?

What quantity is the sum of the kinetic energy and all forms of potential energy in a system?
the total energy U. If there is no work done on the system, Uint= KE+PE
What does the conservation of energy tell you about the total energy of an object?
Total energy of an isolated object is always same.
What is the law of conversation of mass?
the law of conversation of mass states that mass is neither created nor destroyed in a chemical reaction. meaning that the total mass in a chemical reaction doesn't change.
What is true about the total energy in a system?
The total kinetic energy within a system
What is the law of conservation of mass which states that cannot be created or destroyed applies?
The law of conservation of energy, first formulated by Julius Robert Mayer in 1842 , is a law of physics. It states that the total amount of energy in an isolated system remains constant over time. The total energy is said to be conserved over time. For an isolated system, this law means that energy can change its location within the system, and that it can change form within the system, for instance chemical energy can become kinetic energy, but that energy can be neither created nor destroyed.For example, water falling over a waterfall is slightly warmer at the bottom than at the top as some of the potential energy has been changed through kinetic energy into heat energy due to friction between the molecules as they fall.
An application of the first law of thermodynamics is energy does not increase or decrease?
The total energy of an isolated system will never increase nor decrease. Any increase in energy in a closed system (one where no mass crosses the system boundaries) must come by the addition of that energy from outside via heat or work. Likewise any decrease can only come via heat leaving the system or work being done by the system on its surroundings.
What is the total energy of the a system?
The Total Energy of a system is E= Escalar + Evector = Es + Ev.The Total Energy is a Quaternion Energy, consisting of a Scalar/Potential Energy and a Vector Energy Ev= mcV.
What do you need to get energy?
You cannot create energy. You can simply convert energy from one form to another, for example potential energy to kinetic energy - dropping a ball, when the ball is released it has potential energy which is converted into kinetic energy as it falls (plus some heat energy). The total energy of a system has to remain constant, this principle, the conservation of energy, was first postulated in the early 19th century, and applies to any isolated system.
What is the thermal energy of system?
The total kinetic energy within a system
