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.
