QUESTION 2.1: Do you expect heat to flow into or out of the cup into the surrounding atmosphere?
ANSWER: The heat flow is expected to flow out of the cup into the surrounding because temperature of the cup is more than its surroundings.
QUESTION 2.2: Is the difference between the final and initial temperatures, T_f − 푇푖, positive or negative? Explain why you gave the answer you did.
ANSWER: The difference between the final and initial temperatures is negative. This is due to the fact that gas, or liquid, always flows from the region of its higher concentration to the region of its lower concentration. Since the surrounding temperature, at the time of experiment, was 〖17〗^o C which is lesser than 〖23〗^o C, the heat escaped into the surrounding.
