Work is done by the system and heat (q) is supplied to the system. What type of system would it be?

Express the change in internal energy of a system when 1) No heat is absorbed by the system from the surroundings, but work (w) is done on the system. What type of wall does the system have ? ii) No work is done on the system, but a amount of heat is taken out from the system and given to the surroundings. What type of wall does the system have? iii) w amount of work is done by the system and q amount of heat is supplied to the system. What type of system would it be?

The potential energy of a system increases if work is done

The internal energy of a system changes when it undergoes
