Answer:
The correct option is;
decreasing entropy is a nonspontaneous
Step-by-step explanation:
Recycling of aluminium beverage cans involves the process of remelting scrapped beverage after the cans were first produced and used initially
1) The cans are cut into pieces so as to make them more compact and accessible for cleaning
2) The cans are then blocked and melted by heating and the impurities and hydrogen gas are removed
3) The composition of the molten aluminium alloy is altered by the addition of the alloy composition to get the right specification of the alloy
4) The molten alloy can then be sent for usage where it will be processed into solid aluminium objects without the requirement for much energy addition
By the second law of thermodynamics, processes 1, and 2 which involve the addition of energy from the surrounding to decrease the randomness of the scrapped beer cans such that the entropy of the surrounding decreases are not spontaneous processes, while process 4 where the molten aluminium will be cooled down to form solid aluminium does not require energy input but adds energy to the surrounding in the surrounding's entropy, is therefore a spontaneous process.
Therefore, decreasing the entropy of the universe by heating aluminium to melt it is a non spontaneous process
