Best ResponseYou've already chosen the best response.1When a gas expands against a pressure, then the system is doing work on the surroundings. I think you should take a look at the first law of thermodynamics to get a better understanding because this can be quite a tricky subject!

Best ResponseYou've already chosen the best response.1Well when work is done on a system, the internal energy is increased! Compressing a gas inside a thermally insulated container increases the internal energy of the gas.

Best ResponseYou've already chosen the best response.0work doen \(by\) a system is energy \(lost\) by the system to the surroundings as work

Best ResponseYou've already chosen the best response.1I would honestly say it's D but I'm not too sure. It is work done to the system, but the energy is lost to the system
