Answer:
The dissociation of copper sulfate into ions is an exothermic chemical reaction that releases heat into the surroundings.
Explanation:
Some of the potential energy stored in the solid sample of anhydrous copper sulfate is released as heat as the sample dissolves and dissociates into ions in the water. This is due to the large lattice energy of the crystalline copper sulfate.

The answer is; Cosmic background radiation is leftover thermal energy from the big bang.
Called the coming microwave background the weak radiation fills the universe more or less uniformly. This radiation is the fossil remnants of the postulated big band at the beginning of the universe. The photos produced at the time continue to travel through the universe growing fainter over time and have fallen in the microwave range of the electromagnetic spectrum now.
