Flashcards

Pressure and Density Relationship

The relationship between pressure and density of a gas at constant temperature is directly proportional. This means that as pressure increases, density also increases, and vice versa.

Hydrogen Bonding and Boiling Point

Hydrogen bonding is a strong type of intermolecular force. These forces require a lot of energy to overcome, leading to higher boiling points for substances with hydrogen bonds.

Ideal Gas Equation

The ideal gas equation (PV = nRT) relates pressure (P), volume (V), temperature (T), and the number of moles (n) of a gas.

Saturated Vapor Pressure

Once a liquid reaches its saturated vapor pressure, the vapor pressure remains constant. This means that the rate of evaporation equals the rate of condensation.
