Graph of vapor pressure and temperature

WebVapor pressure increases with temperature because molecular speeds are higher as temperature increases. Table 13.5 gives representative values of water vapor pressure over a range of temperatures. Figure 13.31 (a) Because of the distribution of speeds and kinetic energies, some water molecules can break away to the vapor phase even at ... WebFigure 2 shows a graph of pressure versus volume. The hyperbolas represent ideal-gas behavior at various fixed temperatures, and are called isotherms. At lower temperatures, the curves begin to look less like hyperbolas—the gas is not behaving ideally and may even contain liquid. ... vapor: a gas at a temperature below the boiling temperature ...
