yes it can
YesIt is true that solar energy can be changed into thermal energy without any work being done. The solar energy is thermal energy from the sun.
You are made from matter, and therefore would not be able to detect energy without it having an effect on you. Energy is defined as the capacity for doing work. Without work ever being done on matter, and without energy ever being defined this way, energy would not be detected.
work is being done when you use energy

YesYes
Energy is a conserved quantity. That means that, if no energy enters or leaves an object, the total energy of this object will remain the same. There are several ways for energy to enter or leave; I am not sure whether all of these qualify as "work".
Negative work increases potential energy.
computers have done alot other the past 15 years it changed everything and what it has done is made alot of people without a job because people now use the internet and buy there shopping on it. It has changed the world
Done correctly, indefinitely.
No. NOTHING can be done without energy.Well, some organisms could remain dormant for a while, without an energy source. But in the long term, they will need an energy source, to have any type of activity.
without success, or something done for nothing, as a waste of time and energy.
