Question

A system absorbs 2000 joule of heat and delivers 1200 joules of work while losing 200 joule of heat by
conduction to the atmosphere. The change in the Internal energy of the system is?​

Answer 1

Dear Student,

◆ Answer -

Change in internal energy = 600 J

● Explaination -

Change in internal energy of the system is given by -

Change in internal energy = Heat absorbed - Work done - Heat lost

Change in internal energy = 2000 - 1200 - 200

Change in internal energy = 600 J

Hence, change in internal energy of system is 600 J.

Thanks dear. Hope thats helpful...
