Answer #1

Ans : A) Life ; B) Fresh perked coffee cooling down ; C) Lipstick melting on a hot day

The reactions or processes that occur on their own and favor the formation of products in the conditions in which the reaction is tend to occur.

Life occurs spontaneously , we cannot stop life. Likewise fresh perked coffee cooling down , since the heat tend to flow from hot to cold system and lipstick melting on hot day are spontaneous processes.

Cooling of air inside the refrigerator is non spontaneous on a hot summer day as electricity and cooling motor is required to cool the air and it does not occur on its own.
