Pressure in a Gas Melting, Boiling and Evaporation Density

Mass per unit volume Units: kgm-3, gcm-3, gml-1 Density is changes with temperature Relative Density Density of a substance divided density of water

Dimensionless Density of water is 1000 kgm-3 Densities of Some Substances Comparing Densities When most substances change from a solid

state to a liquid state their volume does not change much. Density of a solid is almost the same as a liquid. Comparing Densities When a liquid changes into a gas, the spacing

between the particles increases by a factor of about ten. As a result, the density of a substance decreases by a factor of approximately 1000 when it changes from a liquid to a gas. Sample Calculations

A cup of gold colored metal beads was measured to have a mass 425 grams. By water displacement, the volume of the beads was calculated to be 48.0 cm3. Identify the metal. A 60-ml flask is filled with mercury at 0C. When the temperature rises to 80C, 1.47 g of mercury spills out of the flask. Assuming that the volume of the

flask is constant, find the density of mercury at 80C if its density at 0C is 13,645 kgm-3. Pressure

Force per unit area Force is normal to the area Units: Nm-2, kgm-1s-2, Pascal (Pa) Fluid Pressure

Measuring Pressure Mercury Barometer U-tube Manometer Equation Sample Calculations A U-tube contains liquid of unknown density.

An oil of density 800 kgm-3 is poured into one arm of the tube until the oil column is 12 cm high. The oil-air interface is 5.0 cm above the liquid level in the other arm of the tube. Find the density of the liquid. P400, #22.18 (a)

Kinetic Theory of Matter All matter is made up of a large number of tiny atoms or molecules which are in continuous motion Pressure of a Gas

Force that the gas molecules exert as they hit the walls of the container Energies and Molecules Potential Energy Distance between molecules

Kinetic Energy Related to temperature of the substance Internal Energy The sum of the kinetic and potential energies of a substance.

Melting and Boiling Heat is added to break bonds between molecules Some part of the energy is used to work against the environment Both occur at a specific constant temperature Let us look at the energies involved

Boiling and Evaporation Both involve changes from liquid to gas Boiling occurs at a specific temperature Evaporation occurs at any temperature Boiling occurs inside the liquid Evaporation occurs at the surface of the liquid
