Specific latent heat meaning
WebLatent heat is the heat per unit mass required for a phase change to occur. We may think about what happens when we add ice and cold soda to glass. Since the soda is warmer than zero degrees Celsius. So, we may expect that the heat from the slightly warmer soda to melt the ice in the glass. WebApr 9, 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.
