Ice of mass 10g at 5^\circC was completely converted to water at 0^\circC, calculate the quantity of heat used. [specific heat capacity of ice = 2.1 Jg\(^{-1}\)K\(^{-1}\), specific latent heat of fusion of ice = 336 Jg\(^{-1}\)]
A
105J
B
3255J
C
3465J
D
16821J
Verified Correct Answer: C.
Physical Principles & Numerical Solution
Q = ML + MC\(\theta\)
= 10 x 335 + 10 x 2.1 x 5
= 3465J
