1.	Water falls from a height `500m`, what is the rise in temperature of water at bottom if whole energy remains in the water ? `(J=4.2)`A. `0.96^(@)C`B. `1.02^(@)C`C. `1.16^(@)C`D. `0.23^(@)C`
Answer» Correct Answer - C By the law of conservation of energy JmC dT=mgh `dT=(gh)/(Jc)=(9.8xx500)/(4.2xx10^(3))=1.17^(@)C`
