Question

Your body needs to heat the cold water that you drink to
37.0°C. A slice of cake gives about 1000 kJ of heat when metabolized by your body. How much cold water, at 2.0°C, do you need to drink to make up for (that is, use up the kilojoules gained by) eating a slice of cake?
how would I go about and doing this question? thanks in advance!

Answer 1

Q = m x c x delta T

m (in kg) = c x delta T/Q

c = 4.18
delta T = 35
Q = 1,000 kJ

Now you can do the rest.
