In Part A, you determined that the heat added to the coffee is what you got. If it takes 4.2 J of energy to raise the temperature of 1.0 mL of coffee by 1.0∘C, then it should take twice as much energy to raise the temperature of 2.0 mL of coffee by 1.0∘C, or to raise the temperature of 1.0 mL of coffee by 2.0∘C. Multiply carefully to find the total amount of energy needed to raise the temperature of 200 mL of coffee by the required number of degrees.
The answer is 2.52×10^4 J
Oh this again. Hmm what I understand is, you need 4.2/1 J/ml per degree. So I guess you multiply that by what volume and degree you want?
Yeah, I and another person got this answer for this question, but it was apparently wrong.
The result you say would be 840J right?
Yes. Does it say what degrees you want?
it wants 3 sig figs, but no degrees.
