A certain amount of gas at a pressure of one atmosphere and a volume of ten liters could become five liters if the pressure was increased or would become more than ten liters if the pressure . O Gases form a horizontal surface. We will find that the air takes the shape of the balloon in which it is filled. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. If volume increases, then pressure decreases and vice versa, when temperature is held constant. (b) The molecules of a gas are free to move randomly in all directions. Properties of CNG basis on volume. What do liquids and gases have in common? c) Liquefied petrochemical gas. Let us do some activities to understand the properties of solids, liquids and gases. Gases have the most energy and are the least dense. Liquids do not have a fixed shape and tend to take the shape of the container in which they are kept. They do not have a fixed position or spaces between them. (c) Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. Its particles are still close together but move freely. The very weak intermolecular forces can not hold the molecules within a certain volume, so they move in all the directions in a closed container or in. Matter in the liquid state has a fixed volume, but it has a variable shape that adapts to fit its container. C v =(∂ U/∂ T) v whereas C p for a gas is the change . A gas, on the other hand, has a vol- ume that changes to match the volume of its container. (i) Gases are highly compressible, i.e. Instead, they take the shape and volume of the container, and they fill the container. Its particles are close together and fixed in place. Chemists sometimes make comparisons against a standard temperature and pressure (STP) for reporting properties of gases: 273.15 K and 1 atm (101.325 kPa). Microscopic view of a liquid. A gas fills its container, taking both the shape and the volume of the container. b) Compressed nurture gas. Its particles are close together and fixed in place. Matter in each state exhibits distinct characteristics. Think about the balloon again: the gas fills the entire space inside the balloon.
