Question

Water can be lifted into the water tank at the top of the house with the help of a motor pump. Then why this change is not considered to be spontaneous?

Answer 1

According to the Second law of thermodynamics, all spontaneous process or naturally occurring processes are thermodynamically irreversible.

Entropy of the universe increases in the order of every spontaneous change.

A process which has a natural tendency to occur without initiation is called spontaneous process.

After initiation, a spontaneous process should continue on its own. But this is not so in the given case, because as long as the pump works, water will rise.

Answer 2

HII FRIEND,
A spontaneous process should continue taking place by itself after imitation.
But this is not so in the given case because the water will go up as long as the pump is working
