The discussion centers on a calorimetry experiment involving processed cheese food, where a 20.0 g serving contains 175 Calories. Participants are tasked with calculating the change in temperature of 100.0 mL of water after burning 1.0 gram of cheese. The key question is determining the heat released per gram of cheese burned. The conversation highlights the need for clarity on the caloric value of the cheese and its conversion to heat energy. Ultimately, the experiment aims to connect the nutritional information with practical calorimetry principles.

The nutrition label on a package of processed cheese food indicates that a 20.0 g serving has 175 Calories. To test this you put a small piece of cheese under a can with 100.0 mL of water and burn the cheese. You find that 1.0 grams of cheese was burned to heat the water. Assume that all of the heat released by the cheese was absorbed by the water(let's pretend), what is the change in temperature of the water at the end of the experiment?

I don't even know where to begin
 
Ok. How many calories of heat are released per gram of cheese burnt?

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
