Typically, water runs through the baseboard copper tubing and, therefore, fresh hot water is constantly running through the piping. However, consider a pipe where water was allowed to sit in the pipe. The hot water cools as it sits in the pipe. What is the temprature change, (ΔT), of the water if 190.0 g of water sat in the copper pipe from part A, releasing 2284 J of energy to the pipe? The specific heat of water is 4.184 (J/g) ⋅∘C

Clayton Waller · Answer 1

The formula for change in energy (change in enthalpy) is given as:

ΔH = m C ΔT

where ΔH = change in energy, m = mass, C = specific heat, ΔT = change in temperature

2284 J = 190 g * 4.184 (J/g) ⋅∘C * ΔT

ΔT = 2.87°C
