Thank you for the opportunity to help you with your question! the solution is as such:

The total potential energy = mgh and the increase in internal energy is mc (∆T). So when the complete potential energy is converted into heat energy then,

m * g* h = m * c * (∆T)

(∆T) = m * g* h/ (m * c )

So here ∆ t = 304.3

Please let me know if you need any clarification. I'm always happy to answer your questions.awaiting a positive feedback. thank you.
