An isolated system is a system that doesn't not interact with its surroundings. No interactions at all. No work, no heat transfer. An adiabatic system is one that does not permit heat transfer between the system and its surroundings. It can do work on the surroundings.
Yes. As an example: if you define a refrigerator as your system, the work done on the system causes heat to be expelled from the system to the surroundings. The net heat expelled will be equal to the work input plus the decrease in its thermal energy.
The state of maximum entropy of a system is the state when all the energy available to a system to do work is dissipated and is evened out with that of the surroundings. Therefore, the ability to do work relates to the difference in energy levels between a system and its surroundings. A system will carry on working for as long as there is energy difference between it and its surroundings. When the energy of a system and its surroundings evens out, the system ceases to function. All functional systems try, but fail to reach that equilibrium. The Universe as a system is no different. However, the energy which causes the universe to expand -- termed dark energy, which source remains unknown, cause the Universe to do work on its surroundings. Therefore, as a system, the Universe must receive or must have received its energy from its surroundings.

There are two ways that a substance ( called the System ) may release energy to the Surroundings :( 1 ) Heat may be released by heat transfer from the System to the Surroundings. Heat transfer from the System to the Surroundings requires the System temperature to exceed the temperature of the Surroundings and the presence of one or more heat transfer modes ( conduction, convection, and/or radiation.( 2 ) Work done by the System of on the Surroundings corresponding to a force moving through a distance, such as when the substance expands. Substance confined to a cylinder with a piston may expand, doing work on the Surroundings.

An Endothermic change is the system that absorbs energy from its surroundings.
You can define a system as part of the universe on which you focus your attention. The surroundings include everything else in the universe. In thermochemical experiments, you can consider the region in the immediate vicinity of the system as the surroundings. A major goal of thermochemistry is to examine the flow of heat between the system and its surroundings.

A chemical system consists of the system and the surroundings. If you're dealing with a solution in a beaker, the solution would be the system and the beaker and air would be the surroundings.
An open system is one that exchanges both matter and energy with its surroundings. For example, suppose Earth is a system and the universe is its surroundings. Earth is an open system, since it can exchange both energy and matter with its surroundings.
