Concept-Development 23-1 all matter can exist i ' ' ' low tempera , m: 151:3:th liquid, or gaseous phases. The solid phase exists at relatively [enlpemturestms. Water is the mp ase at higher temperatures. and the gaseous phase at still higher became the tem Ham f ost common example. not only because of its abundance but also - p s or all three phases are common. Study Section 23.8 in 'our textbook and then answer the followmg: y : Change of Phase 1, How many calories are needed to chan e 1 gram ' of 0C ice to \\x'ater? g ICC-3E , How many calories are needed to change the temperature of 1 gram of water by 1C? . How many calories are needed to melt 1 gram of 0C ice and turn it to water at a room temperature of 23C? 4. A SO-gram sample of ice at 0C is placed in a glass beaker that contains 200 g of water at 20C. as How much heat is needed to melt the ice? b. By how much would the temperature of the water change if it gave up this much heat to the ice? c. What will be the nal temperature of the mixture? (Disregard any heat absorbed by the glass or I=> given off by the surrounding air.) 5. How many calories are needed to change 1 gram of 100C boiling water to 100C steam? the state of 1 gram of 0C ice to 100C 6.
