Comparison of solids, liquids, and gasses Fluids flow freely Condensed states have higher density than gas Vapor refers to a gas that is formed by evaporation of a liquid or sublimation of a  solid Volatile liquids are easily converted to gas at room temperature. All gasses are miscible-- they do not mix completely with one another, unless  they react with each other Composition of the Atmosphere and some common properties of gasses Gasses can be compressed into smaller volumes o Their densities can be increased by applying increased pressure Gasses exert pressure on their surroundings o Pressure must be exerted to the confined gas Gasses expand without limit o Therefore they occupy the volume of any container Gasses diffuse into one another o So they mix complete in containers o They do not separate on standing The amounts and properties of gasses are described in terms of temperature,  pressure, volume occupied, and number of molecules present Pressure Pressure is force per unit area Barometer is used to measure atmospheric pressures Manometer is a glass U-tube partially filled with mercury Atmospheric pressure varies with atmospheric conditions and distance above
