**Question 6**On a spring afternoon in Georgia, Stephen, a vegetable grower, heard that the National Weather Service had issued a freeze warning for that night and forecasted the temperature to fall just below 0°C. He wanted to protect his plants, so he waited until dusk and showered them with as much water as he could. The next morning, he saw that the plants had been saved.**Cooling Curve for One Gram of Water**The graph provided is a cooling curve for one gram of water, showing the relationship between temperature (°C) and heat flow (Joules). Here’s a detailed explanation of the graph segments:- **A to B**: Rapid decrease in temperature as the water begins to cool.- **B to C**: Temperature remains constant at the boiling point as heat is removed. This indicates the phase change from gas to liquid (condensation).- **C to D**: Linear cooling of liquid water.- **D to E**: Temperature remains constant at the freezing point as heat is removed. This indicates the phase change from liquid to solid (freezing).- **E to F**: Linear cooling of solid ice.- **F to G**: Further decrease in temperature as ice cools below the freezing point.**Question:**If the water Stephen used was at a temperature of 40°C, which segment or segments of the cooling curve represent the process that saved the vegetable plants?- **A**: DC- **B**: DE- **C**: DC & DE- **D**: DE & EFThe answer will indicate which phase changes or cooling processes are relevant to Stephen's situation, considering the initial water temperature and the expected temperature drop.

Children asked their parent for an ice cream after dinner. They eat their ice cream as long as it does not melt and its structure is solid. The parent drove to buy an ice cream in the grocery store. The ice cream is sold in family sized package. The store keeps the ice cream packages in the freezer until it is sold. The packages are made from polystyrene material and their size is 0.2´0.1´0.07 m3 . The store freezer temperature is kept at -10o C. The ice cream has a solid structure (not melting) as long as its temperature remains below 0o C. The time it takes to reach back from the store is 20 minutes Will the kids eat the ice cream at home? Ice cream properties: k = 2.2 W/mo C, C = 1800 J/kgo C, r = 900 kg/m3 and h = 10 W/m2oC.
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

4 2 MOHR CIRCLES PROBLEM You've been working in the lab to determine the strength of an altered granitoid which hosts mineralization. The company you work for wants to start a deep underground mine in the region and it is imperative that the strength of the altered granitoid is well characterized. You conduct a series of experiments on the granitoid to develop a Coulomb failure criterion for the altered granitoid. All of your experiments were conducted in dry conditions (i.e., no pore fluid pressures). Plot up your 3 experiments as Mohr circles, fill in the table below, and determine the Coulomb failure criterion for the altered granitoid.
