Question

Do you have enough fuel to melt your watert nom dw mi 2) Should you stick With Sir Chemisuy Reli Day 23. Step 3: Day 20 You blaze up the mountain and Step 5: Day 20 You blaze up leave Sir Reference Table in the dust. Unfortunately, you forgot to pack more fucl and have only 1,000,000 joules of fuel left. Furthermore, all of your 3,000 grams of water has frozen. You need all of your water to survive the climb. How much fuel energy is needed to melt all the water? Equation needed: If not, how much more joules do you need? You should have never abandoned your friend! Because you don't have enough fuel, you don't have enough water to drink. Your journey ends here as you die from dehydration. Now go on to Day 23 to see what would've happened if you didn't abandon your friend Equation I needed: Step6: Day 23 Congratulations! You have climbed for 22 days, endured strains in your friendship with Sir Chemistry Reference Table, went through several snowstorms, almost fell off an edge, and almost quit. You've finally reached the summit! You want to celebrate this achievement with your best friend by cooking a nice meal. 9 Equation 2 needed:_ There are 2,000 grams of ice in your cooking pot. The temperature reads -10 °C and your food needs to be cooked in water at a temperature of 70°C. How much fuel is needed to melt the ice and heat the water to the proper temperature? 9 Total energy from both equations: Before you tackle this problem, SKETCH a heating curve of water as it is described in the problem. For your final celebration, both of you toss all of your water bottles off the mountain to watch it fall down. Suddenly, Sir Reference Table says, "Don't we need the water for our descent down the mountain? Your face turns as white as the snow at your feet as you say, "Uh oh.... Time
