My question:
Consider an isolated system consisted of a ball, and a bucket of water. The ball is released from height, H above a bucket of water. The initial temperature of the water-bucket system and the ball are T1 and T2 respectively. What will be the final temperature of the water after the ball is dropped? (mass of the ball = m1, mass of water = m2, mass of the bucket = m3, specific heat of ball, water and bucket are s1, s2 and s3 respectively)
The answer:
mgH = (m1S1+m2S2)T1 + m3S3T2
My problem (Conservation of energy):
We know energy cannot be created or destroyed but it can be converted from one form to another, which is known as the conservation of energy.
But why potential energy should convert into thermal energy? Again if we consider that potential energy is converted into thermal energy why the whole energy should be converted?
I mean some energy should be converted. Suppose, the amount of the converted energy is E. Then,
mgH -E= (m1S1+m2S2)T1 + m3S3T2+E
So, can you please explain the matter easily?
