- Heat transfer during phase change (melting or freezing) involves latent heat ($Q = mL$). - Heat transfer during temperature change involves specific heat ($Q = mc\Delta T$). - Need to account for heat required for each component (ice and water) and each process (heating ice, melting ice, heating water).
10 g of ice at $-10^\circ$C is mixed with 10 g of water at $0^\circ$C. The amount of heat required to raise the temperature of mixture to $10^\circ$C is
