版权所有：华东理工大学物理化学教研室 32 a). Boyle’s Law- at constant T At constant T, p and V of a fixed amount of gas are related by pV = constant Each of the curves in the graph corresponds to a single T and is called an isotherm. According to Boyle's law, each of the isotherms is hyperbola. 1.2 The gas laws — 1).Three important gas Laws The p-V dependence of a fixed amount of perfect gas at different T. 32
