    Study Notes

    States of Matter

    • A solid has a definite shape and volume at a given temperature and pressure.

    Phase Transitions

    • Water transitions into the gaseous state at 100°C (boiling point).
    • The triple point is the temperature and pressure at which all three phases (solid, liquid, and gas) of a substance coexist in equilibrium.

    Plasma

    • Plasma is often referred to as the fourth state of matter.
    • Plasma exists at very high temperatures.

    Phase Equilibrium

    • Water has all three phases in equilibrium at a pressure of 611.73 Pascals and a temperature of 0.01°C (triple point).

    Gas Properties

    • Pressure and the gaseous state are directly related: as pressure increases, the volume of a gas decreases.
    • The number of moles of a gas is directly proportional to its mass.
    • Volume is expressed in terms of liters (L) for gases.
    • Temperature in the context of gases is the measure of the average kinetic energy of gas molecules.

    Pressure and Altitude

    • Atmospheric pressure decreases with altitude.
    • The SI unit of pressure is the Pascal (Pa).

    Temperature Scales

    • The Celsius scale measures temperature, with 0°C being the freezing point and 100°C being the boiling point of water.
    • The Fahrenheit scale measures temperature, with 32°F being the freezing point and 212°F being the boiling point of water.
    • The Kelvin scale is the absolute temperature scale, with 0 K being absolute zero.
    • The conversion from Celsius to Fahrenheit is °F = (°C × 9/5) + 32.

    Gas Interactions

    • The force experienced by the walls of a container due to gas molecules' bombardment is pressure.

    Standard Atmospheric Pressure

    • The standard atmospheric pressure at sea level is 101,325 Pa, equivalent to a mercury column height of 760 mm.

    Molar Mass

    • The molar mass of a gas is the mass of one mole of the gas.
    • The molar mass is proportional to the mass of a gas.
