Is the melting point of ice a physical or chemical property?

WebThere is an inverse relation between the pressure and the melting point of ice which is known to all. So when the pressure increases on the ice,its volume decreases more. Hence the melting point of ice also decreases. It means that in the case of an ice water system the melting point is inversely proportional to the pressure. WebThe melting point of ice = temperature when the ice starts melting (t 1) + temperature at which ice completely melts (t 2) ÷ 2. Melting point of ice = t 1 + t 2 ÷ 2.
