Answer:
5511 J
Explanation:
Applying,
Q = Cm.................... Equation 1
Where Q = amount of heat required to convert ice, C = Heat of fusion of water, m = mass of ice
From the question,
Given: C = 334 J/g, m = 16.5 g
Substitute these values into equation 2
Q = 334(16.5)
Q = 5511 J
Hence, the amount of heat required is 5511 J
A temperature change in a reaction indicates a chemical change
D.
The water must be heated and removed in distillation, so thermal energy is required.
