A solid of mass 0.5kg initially at 50oC melts at 60oC. Calculate the quantity of heat required to melt it completely. [specific heat capacity of the solid =2.0KJ kg-1K-1][Specific latent heat of fusion of solid =1.0 KJ kg-1]
A
1500J
B
10000J
C
10500J
D
15000J
Verified Correct Answer: C.
Physical Principles & Numerical Solution
Q = ML + C\(\theta\)
= 0.5 x 1000 + 0.5 x 2000 x 10
= 10500
