Exercise:
A pq.kg aluminium sphere is dropped from the roof of a pqm high building. If % of the thermal energy produced when it hits the ground is absorbed by the sphere what is its temperature increase?

Solution:
The potential energy of the aluminium sphere on the roof is Epot mgh pq.kg pqNpkg pqm pq.J. % of this energy will heat up the aluminium sphere i.e. Q . Epot pq.J. The temperature increase hence will be Deltatheta fracQcm fracpq.JpqJpkgK pq.kg pq.Celsius.
