Question

A system absorbs 10 kj of heat at constant volume and its temparature rises from 27 c to 37 c . the internal energy of reaction is

Answer 1

Answer:

the internal energy is equal to heat absorbed

Answer 2

Answer:

∆U=10 KJ

hope you find it useful pls comment

Explanation:

..

Since

∆H = ∆U + P∆V,

and P∆V represent work done

as, Volume is constant and temperature rises this means that the heat absorbed is completely converted into internal energy

Therefore,
