SATHEE: Properties Of Solids And Liquids Question 82

Properties Of Solids And Liquids Question 82

Question: A stationary object at 4°C and weighing 3.5 kg falls from a height of 2000 m on a snow mountain at 0°C. If the temperature of the object just before hitting the snow is 0°C and the object comes to rest immediately $(g = 10 m / s^{2})$ and (latent heat of ice $= 3.5 \times 10^{5} j o u l e / \sec$ ), then the object will melt [BHU 2001]

Options:

A) 2 kg of ice

B) 200 gm of ice

C) 20 gm ice

D) 2 gm of ice

Show Answer

Answer:

Correct Answer: B

Solution:

Suppose m kg of ice melts then by using $\underset{(Joules)}{W} = \underset{(Joules)}{H}$

therefore $M g h = m L$ therefore $3.5 \times 10 \times 2000 = m \times 3.5 \times 10^{5}$

therefore $m = 0.2 k g = 200 g m$
