1. The problem statement, all variables and given/known data Hi Lets say I heat 50g of water to 80°C. I take another 50g of room temperature water and put it in a bowl. Then I add this 50g of heat water to the bowl, the temperature in the bowl goes from 25°C to 48°C. What is the amount of heat absorbed by the room temperature water? 2. Relevant equations Is it Q = (50g)(4.18 J/(g*k))(48-25) or Q = (100g)(4.18 J/(g*k))(48-25) 3. The attempt at a solution Do you add the solution of water in the mass or just use 50g=mass in the equation?
