An isolated system is one in which no external forces act.
answer2.
Energy and mass remains constant in an isolated system.
the amount of matter
number of organisms
If it is a closed system, the total energy remains equal.
The total mechanical energy of the system remains the same.
The first law of thermodynamics states that the energy of an isolated system is constant.
To be honest, I was searching "The internal energy of an isolated system is" to get an answer myself. However, in the light that energy is constant, that makes a lot of sense. The internal energy is constant in an isolated system because external factors cannot change what is occurring in such a system. The energy is therefore constant considering equilibrium. Over time, the rate of anything will become stabilized, such as when there is a gas-liquid equilibrium and rate of condensation = rate of vaporization. In short, it's constant because of equilibrium and the fact that outside things have no effect.
: a principle in physics: the total electric charge of an isolated system remains constant irrespective of whatever internal changes may take place
The entropy does not remains constant if the system is not isolated.
If it is a closed system, the total energy remains equal.
The total mechanical energy of the system remains the same.
The first law of thermodynamics states that the energy of an isolated system is constant.
It's Angle modulated system where the amplitude remains constant & frequency & phase varies with respect to modulating signal.

Combined gas law states:" The ratio between the pressure-volume product and the temperature of a system remains constant: p.V = k.T "k is a constant which only is proportionally depending on the amount of gas.
The second law of thermodynamics, generally stated, is that the entropy of an isolated system always increases in any natural process where change occurs. In a system at equilibrium, of course, the entropy remains constant.
the modulation system is of FM
The idea is that you can define a quantity, called "energy", that remains constant over time. That is, if no energy escapes from a system, and no energy comes into a system, the total amount of energy will remain constant. Note that there are different types of energy, and you can convert between the different types - but the TOTAL amount remains constant.
Molality of a solution remains constant as mass of a solution independent of temperature.
