0.37g
0.60g
2.40g
2.70g
Correct answer is D
Mice = \(\frac{MC}{\theta}\)
= \(\frac{20 \times 0.4 \times 110}{330}
Heat lost by copper = Heat gained by ice
m\(_{copper}\) c \(\theta\) = m\(_{ice}\) L
20 x 0.4 x (110 - 0) = m\(_{ice}\) x 330
m\(_{ice}\) = \(\frac{20 \times 0.4 \times 110}{330}\)
= \(\frac{8}{3}\)
= 2.67 g
= 2.70g (to 1 d.p)
