Webc is the specific capacity and. ΔT is the change in temperature. Therefore; Since density of water is 1 g/mL, and specific heat of water is 4.18 J/g°C while the change in temperature is (24-22) = 2°C. Heat absorbed by water = 32 g × 4.18 J/g°C × 2. = 267.52 Joules. Heat absorbed by water is equivalent to heat released by copper.
