Fundamental Facts and Concepts
Experience teaches us, that under given external conditions a material is in a certain state. This state is defined by certain properties. At 200 K the compound H2O is solid, at 300 K liquid and at 400 K gaseous. Properties, which are characteristic for a state of a material, are called intensive properties. Among them is the molar volume. As one can see from Fig. 1.1, the molar volume of water is different at 200, 300 and 400 K.
