A bag filled with lead shots is dropped from a height of h = 22.9 m. The total mass of the bag is m = 620.0 g. What is the increase in the temperature of the lead shots, after the bag hits the ground? The specific heat of lead is c = 130 J/kgK.

Step 1

Given,

Height, h = 22.9 m

Mass, m = 620.0 g

Specific heat, c = 130 J/kgK

We know that, 1 J = 1 kg m2/s2

⸫ Specific heat, c = 130 kg m2/s2kgK = 130 m2/s2K

Increase in temperature, △T = ?

Step 2

Energy (E) after the bag hits the ground can be given as:

Step 3

The specific heat (c)...
