Diagramwhat happens when compounds are heated
WebSuppose you have a pure substance at three different sets of conditions of temperature and pressure corresponding to 1, 2 and 3 in the next diagram. Under the set of conditions at 1 in the diagram, the substance would be a solid because it falls into that area of the phase diagram. At 2, it would be a liquid; and at 3, it would be a vapour (a gas). WebAug 24, 2024 · Heat is the total energy contained within a substance. As a solid is heated, its temperature increases as the molecules move faster.
