Question
Hailstone at 0oC falls from a height of 1 km on an insulating surface converting whole of its kinetic energy into heat. What part of it will melt be :-
Options
A.
B.
C.
× 10
× 10D.All of these
Solution
M = mass of hallstone falling
(m = mass of hallston melting)
As MgH = mL.
So
(m = mass of hallston melting)
As MgH = mL.
So
