    It's the question about the peanut. There is just an arrow on my answer sheet... no answer. Thanks!

    C. ten peanuts=50 kcal, therefore 1 peanut=5 kcal.

    Wait, wouldn't the answer be B, 1 kcal?

    Using Q=MCT and solving for Q:

    Q= (1000 grams) x (1 J/(gxC)) x 50C

    I got 50,000 Joules. Divide by 10 for to get 5,000 Joules per peanut. 5,000 Joules = 1 Kcal.

    Did I mess something up?

    Don't use c = 1 J/g C because that's wrong. c = 1 cal/g C

    So...

    q = (1000 g) (1 cal/g C) (50 C) = 50,000 cal = 50 kcal for 10 peanuts.

    5 kcal = 1 peanut
