Study Notes
- The three phases of matter are solid, liquid, and gas, which differ in shape, volume, forces of attraction among particles, and arrangement of particles.
- Ludwig Boltzmann and James Clerk Maxwell explained the physical properties of gases in terms of the motion of individual molecules.
- The kinetic molecular theory of gas states that gas molecules are far apart, in constant random motion, exert no attractive forces on one another, and have an average kinetic energy that depends on temperature.
- The physical quantities of a gas include pressure, volume, temperature, and amount of substance.
- Pressure is defined as force divided by surface area and is measured in atm, mmHg, torr, or kPa.
- Volume is the space occupied by matter.
- Temperature affects the behavior of gases, with higher temperatures causing faster molecular motion.
- Amount of substance is measured in moles.
- Boyle's Law states that the pressure of a gas at a constant amount and temperature is inversely proportional to its volume.
- The mechanism of a syringe works based on the relationship between pressure and volume.
