Question

If 3000J of work is done on the system by the surrounding and 400J of heat is evolved by the system calculate the internal energy change and enthalpyc of the system

Answer 1

Answer:

we know that

Q=U+W

Q=heat energy

U=internal energy

W=work

given

      work=3000J , evolved heat=-400J

U=?

U=Q-w

U=-400-3000

U=-3400J

i.e., system of 3400J of internal energy is converted into work and heat
