Question

.
3. The terms hot and cold are used in relative context. Explain.
4. Give an example of electrolytic de comunion​

Answer 1

Answer:

when we put the hand in the warm from the cold water, our hand will absorb heat, causing the hand to feel hot. Thus, we can conclude that the more heat it absorbs, the more hotter it is. Whereas the more heat it releases, the colder it is. Hot and cold are relative terms, nothing is absolute hot or cold.

Some other examples for electrolytic decomposition reaction used in metallurgy are refining of copper and silver. Recycled silver is recovered through electrolysis which produces crystal silver.
