Question

find the change in the internal energy of the gas as it moves from c to d. the change in the internal energy of the gas as it moves from a to c is -100 j and 90 j of her energy must be transferred to the gas during the process c to d. an additional transfer of 40 j to it as heat is needed as it moves from d to a

Answer 1

Answer:

i dont know the answer but i am writing just to get 5 points

Answer 2

Answer:

60 joules

Explanation:

Total energy along a cycle is zero

-100+E(cd) +40 = 0

that implies E(cd) = 60 J
