NEET Physics Heat Transfer MCQ Question
A piece of ice falls from a height h so that it melts completely. Only one-quarter of the heat produced is absorbed by the ice and all energy of ice gets converted into heat during its fall. The value of h is: [Latent heat of ice is 3.4 × 10⁵ J/kg and g = 10 N/kg]
34 km
544 km
136 km
68 km
Correct Answer
Detailed Explanation
The potential energy lost is converted into heat, and only one-quarter of it is absorbed by the ice. Using the latent heat formula, the height h is calculated to be 136 km.
