When is the total heat observed by the system during the process used up in work? |
|
Answer» udent,◆ Answer -Total heat obsorbed by the system during the process is used up in work when internal energy of the system remains constant.● Explaination -FIRST law of thermodynamics states that the change in the internal energy of a closed system is EQUAL to the AMOUNT of heat supplied to the system, minus the amount of work done by the system on its surroundings. Change in internal energy = Heat absorbed - Work done Heat absorbed = Work done + change in internal ENERGYWHEN change in internal energy is zero, Heat absorbed = Work doneThanks dear. Hope this helps you... |
