What is the quantity of heat required to convert 20 g of ice at 0 ºC to water at the same temperature? (Specific latent heat of ice = 336 Jg\(^{-1}\))
A
7.06 x 10\(^{3}\)J
B
5.38 x 10\(^{3}\)J
C
6.72 x 10\(^{3}\)J
D
1.35 x 10\(^{3}\)J
correct option: c
Quantity of heat = mass * specific latent heat
=> 20 * 336
Quantity of heat = 6720j
= 6.72 x 10\(^{3}\)J
