Question

40g of 0°C ice is placed in 100g of liquid water at 15° C. How much ice melts? (See the formula sheet
for properties of water.)
O 11.7g
O 26.4g
O 40.0g
O 18.8g

Expert Solution

Step 1

The ice can absorb heat available in the liquid water such that the system reaches in thermal equilibrium.

The heat released by the water while reducing its temperature from $15 ° C$ to $0 ° C$ will be;

$Q = m_{water} c_{water} Δ T Q = (0.100 kg) (4186 J/kg \cdot ° C) (15 ° C - 0 ° C) Q = 6279 J$
