A gas burner transfers 9.20 × 105 J into a block of ice with a mass of 2.29 kg and an initial temperature of 0°C. (a) How much of the energy (in J) supplied by the burner goes into melting all the ice into liquid water? (Enter you answer to at least three significant figures.) 769440 ✓ Melting is a phase change from solid to liquid and requires an energy transfer of Q = mL, where Lf latent heat of fusion. Freezing is a phase change from liquid to solid and requires an energy transfer of Q = -mLp In freezing, the energy transfer is negative because energy is removed from the substance. J (b) How much of the energy (in J) supplied by the burner goes into raising the temperature of the liquid water? (E your answer to at least three significant figures.) 1.57E+5 Think about conservation of energy. The total energy supplied is known, and you found in part (a) the energy goes into melting. How much is left over? J (c) What is the final temperature of the liquid water in degrees Celsius? 15.65 Use the energy found in part (b). How does it relate to mass, specific heat, and temperature change? What is initial temperature? °C
