Question

328J of work is done by the system on it's surrounding by absorbing 145J of heat.what is the change in internal energy during the process?​

Answer 1

Answer:

328 answer

Explanation:

A system absorbs 180 J of heat i.e. q= 180 J does 160 J of work i.e. w= -160 J because work done by the system change in internal energy =x J thanks.

i hope help you

Answer 2

Answer:

Given:

• Work done by the system,W=-328J(As work is done by the system,so it is negative)
• q=+145J( As Heat is absorbed by the system,So it is positive)

To find:

• Change in internal energy during the process,∆U=?

Solution:

According to the first law of thermodynamics,

∆U=q+W

∆U=145-328

∆U=-183J

Thus, The internal energy decreases by 183J.
