Question

Hailstone at zero degrees Celsius falls from a height of 1 km on inserting surface converting the whole of its kinetic energy into heat. Which part of it will melt? (J is equal to 10 m²/s², latent heat of ice is equal to 80 calorie/g)

a. 1/8​
b. 1/10​
c. 1/4​
d. 1/2​

Answer 1

To determine which part of the hailstone will melt, we need to calculate the amount of heat transfer required. However, the question does not provide the mass of the hailstone, so we cannot determine which part will melt.

Step-by-step explanation:

To find out which part of the hailstone will melt, we need to calculate the amount of heat transfer required to melt the hailstone. The heat transfer necessary to melt 1.00 kg of ice is given by the equation Q = mLf, where m is the mass and Lf is the latent heat of fusion. In this case, the mass of the hailstone is not given, so we cannot determine which part of it will melt. Therefore, the correct answer is not given in the options provided (a, b, c, or d).
