How do i calculate the amount of heat required to raise the temperature of an 89 sample of water from 40 to 60.
q = mass water x specific heat water x delta T.
You have mass of water (no units---I suppose grams), Specific heat of water is 4.184 J/g*C and delta T is 60-40=20 IF those are degrees. You don't use units because you think they aren't important? Shame.
