Hot Cup

(Easy 10 points) You spill a hot cup of soup into your lap. Which of the following statements are true?

You spill a hot cup of soup into your lap. Which of the following statements are true? (Assume that there are no energy transfers between anything except the soup and your lap.)

a.qsoup is negative.
b.Energy is transferred to the soup.
c.Tsoup is positive.
d.-qlap = qsoup

Which ones are they and why so I can understand? 10 piints to best answer!

Energy must conserved. Heat is transferred from the hot substance (soup) to the cold substance (your lap). Therefore, the only true statement is (d): the heat gained by the lap (-q) is equal to the heat lost by the soup (q).

============= Follow up ===============

Based on 40 years of teaching thermochemistry, I can safely say that Trevor and I are correct and Noah and Neon are not.
