Calculate the amount of heat released when 18.0 g of liquid water at 2

1.	Calculate the amount of heat released when 18.0 g of liquid water at 24.5 degrees C cools to ice at -10.0 degrees C.
Answer» Answer: o far we have discussed temperature change due to heat transfer. No temperature change occurs from heat transfer if ice melts and becomes LIQUID water (i.e., during a phase change). For example, consider water DRIPPING from icicles melting on a roof warmed by the Sun. Conversely, water FREEZES in an ice tray cooled by lower-temperature surroundings. Heat from the AIR transfers to the ice CAUSING it to melt. (credit: Mike Brand
