WebCooling curve. A cooling curve of naphthalene from liquid to solid. A cooling curve is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid. The independent variable (X-axis) is time and the dependent variable (Y-axis) is temperature. [1] Below is an example of a cooling curve used ... WebThe melting point of a substance at a given pressure, P, is the temperature for which its solid and liquid phases are in equilibrium at that pressure. This roughly vertical line, then, is a plot of the melting point of the substance as a function of pressure. The normal melting point of a substance is its melting point at a pressure of 1 atm. WebMelting Point and Boiling point- Melting point is a characteristic property of solid crystalline substances. It is the temperature at which the solid phase changes to the liquid phase.This is the point at which both liquid and solid phases exist at equilibrium.Visit BYJU’S to learn more about the Principle, Detailed Explanation, Videos and FAQs of … port orlando parking
