CHANGE OF PHASE: Matter can exist in solid, liquid, or gaseous phases. Solids exist at the lowest temperature for a material, liquids at a higher temperature, and gaseous phase at the highest temperature. It is easier to observe these changes with water because of its abundance and the temperatures for each phase. After studying change of phase in you text answer the following: 1. How many calories are needed to change I gram of OC ice to water? 2. How many calories are needed to change the temperature of I gram of water by 1.C 3. How many calories are needed to melt I gram of 0 "C ice and turn it to water at a room temperature o 23 .C ? 4.

By how much would the temperature of the water change if it released this much heat to the ice? c. What will be the final temperature of the mixture? (disregard the glass and surrounding air) 5.
