How is latent heat transferred
WebAt 100∘C, 100 ∘ C, the water begins to boil and the temperature again remains constant while the water absorbs 539 cal/g of heat during this phase change. When all the liquid has become steam vapor, the temperature rises again, absorbing heat at a rate of 0.482 cal/g⋅∘C. 0.482 cal/g ⋅ ∘ C. Figure 3. Web9 apr. 2024 · When immersed in a steam current at 100°C, 0.5g of the steam condenses on it. Provided that the latent heat of steam is 540 cal/g, calculate the specific heat of the metal. Sol: Let c be the specific heat of the metal. Heat gained by the metal. Q = mcΔt. ⇒ Q = 60 x c x (100 - 20) ⇒ Q = 60 x c x 80 cal.
