The motor does 20 J of work on the block, it means that the total mechanical energy of the block has increased by 20 J. But the increase in total mechanical energy is equal to the sum of the increases in potential energy and kinetic energy:
So, if the gravitational potential energy has increased by 15 J, the kinetic energy has increased by
1665183.6J
Explanation:
Given parameters:
Mass of Gold = 12400g
Initial temperature = 23°C
Final temperature = 1064°C
Unknown:
Energy required to melt = ?
Solution:
The amount of heat required to cause this temperature change to heat the gold bar is given as;
H = m c Ф
m is the mass of gold bar
c is the specific heat capacity of gold
Ф is the heat change
Specific heat capacity of gold = 0.129J/g°C
H = m c (Ф₂ - Ф₁)
H = 12400 x 0.129 x (1064 - 23) = 1665183.6J
