1kg of copper is transferred quickly from boiling water to a block of ice. Calculate the mass of ice melted, neglecting heat loss. [specific heat capacity of copper 400Jkg-1K-1 and latent heat of fusion of ice 333 x 103Jkg-1]

A.

60g

B.

67g

C.

120g

D.

133g

Correct answer is C

Heat lost = heat gained

1 x 400 x (100 - 0) = m x 333000

m = 0.12kg

converting to grams; 0.12 x 1000

= 120g
