5 40 Pts A Cup Of Water About 240 G Is Poured Into A Saucepan Then Overed With A Lid And Placed On The Stove Supp 1 (42.93 KiB) Viewed 56 times

5. (40 pts) A cup of water (about 240 g) is poured into a saucepan, then overed with a lid and placed on the stove. Suppose the water starts at room temperature of 23 °C, and is heated by the stove which provides 720,000 J of energy eat. The water boils at 100 °C and continues to increase temperature as steam. For water, ice = 2.1 J/(8°c), Cliquid = 4.2 1/18°c), steam - 2.0/18°c), Lusion = 330 1/8, and Lvapor = 2300 J/g. 9. (10) Sketch a graph of the water temperature vs heat added, explaining in a few words the significance of each diagonal, horizontal, and vertical part of the graph. 1. (10) Calculate the energy required to heat the water to 100 °C, the boiling point of water. s. (15) Determine the final temperature of the water after providing the full 720,000 J of heat. t. (5) Using the James Joule water experiment setup, determine a mass and height combination that would provide an equivalent 720,000 1 of mechanical work to the water. (Hint: there are many possible answers, you only need to provide one valid set of numeric answers.)
