I . An adiabatic system consisting of a thermally insulated reaction vessel with a 10 R resistance heater inside is connected to a 20 V

power supply, which is switched on for 50 s.

(i) Analyse the change in internal energy AU of the system.

(ii) Repeat the analysis for an isothermd diuthermic system (i. e. the

system is in contact with a thermal reservoir such as a water bath).
