Question

a) A metal ball of specific heat capacity 400JKg 'C' is allowed to fall from a height of
100m. If the ball on hitting the ground stops and the energy possessed by it is converted
into heat energy, calculate the rise in temperature of the ball. g=10m/s).​

Answer 1

Explanation:

according to the energy conservation

potential energy possessed by body at top = heat energy

m x g x h = m x s x ∆T

10 X 100 = 400 X ∆T

∆T = 2.5 ⁰C

Answer 2

Explanation:

delta t is 2.5 degree celcius
