How is heat lost
WebAccording to Fourier’s law of heat conduction, 2,3 the rate of heat. flow out of the cup is equal to. Eq.2. In this equation, ΔQ is the amount of heat flowing out of the cup during a small time interval, Δt. We used one-minute time intervals in our model. Thus Δt = 1.00 minute = 60.0 seconds. Web19 sep. 2024 · How do you calculate heat lost by metal? Thus: Heat lost by the metal = heat gained by the water, or Qmetal = (∆Tm) (mm) (sm) = Qwater = (∆Tw) (mw) (sw) where the subscripts m and w identify the metal and the water. In this equation, you will know both ∆T values because you will measure initial and final temperatures. What is the unit of …
