Question

3up UL MOUNTAIN CHALLENGE Name: Name: You're on a special suy Reference Table to climb MO la special expedition with your best friend, Sir mountain in the ce Table, to climb Mount Everest, the tallest World at 29,000 feet above sea level. That's not more than 200 corpses litter the mountain (it is y don't rot and it is easier to leave them where One in six climbers dies trying to climb the easy task as more than 200 cores litter so cold, the people die) mountain To survive in this harsh environment you are going to have to ater so you won't dehydrate. Sir Chemistry Reference keep yourself warm and make drinking water he necessary tomation to help YOU DECIDE how much fuel to burn. Table will provide all the necessary be used to meltic to provide water for you and Sir Chemistry Reference The fuel you burn will be used to me Table to drink. Do you have the chestry skills to survive A. Before you begin the climb, S c . A constant is a factor that does not change and for each Chemistry Reference Table says to you le says to you, pure suhe pure substance, a constant value exists that shows how it "My good friend, in order to survive, interacts with heat. Use Table B to find values for water. you need the three heat equations on Physical Constants For Water Table T." Symbol Name Value Unit What are the three heat equations? Ср B. Which terms are variables in the heat equations? A variable is a factor that changes. For each variable shown, record their meaning and their unit. D. When do you use me? Sir Chemistry Reference Table says, "Now that you've found all the heat equations and understand their meanings, how do you know when to use which one? To help you figure that out, the answer to this question may help: "What happens to the temperature of a substance during a phase change? Temperature remains Situation Heat Equation to use Temperature change Variable Meaning Unit Melting (fusion) or freezing Vaporization (evaporation) or condensation
