Properties Of Solids And Liquids Question 111

Question: If two balls of same metal weighing 5 gm and 10 gm strike with a target with the same velocity. The heat energy so developed is used for raising their temperature alone, then the temperature will be higher

Options:

A) For bigger ball

B) For smaller ball

C) Equal for both the balls

D) None is correct from the above three

Show Answer

Answer:

Correct Answer: C

Solution:

Energy = $ \frac{1}{2}mv^{2} $ = mc Dq;

therefore $ \Delta \theta \propto v^{2} $

Temperature does not depend upon the mass of the balls.
