How much heat energy is released to surrounding when 15.0 g of water at 35°C is converted into ice with a temperature of -45°C?
vap = 2260 J/g; Hfus = 334 J/g; Cp(ice) = 2.06 J/g • °C; Cp(water) = 4.18 J/g • °C;
Cp(steam) = 1.99 J/g • °C
Similar to your first post. You work it out. Post your work if you get stuck.
