Study Notes
Thermodynamics
Thermodynamics is a branch of physics concerned with heat and temperature, their relation to energy, and their effects on matter. It involves extensive study of the physical changes that accompany chemical reactions or physical processes that occur under constant pressure and temperature. Thermodynamics is divided into three main branches: classical thermodynamics, statistical thermodynamics, and non-equilibrium thermodynamics.
Ideal Gas Law
The ideal gas law refers to the behavior of gases when their molecules do not interact with each other. This implies that there is no force between the particles, which would cause them to stick together. Under these conditions, the gas behaves as if it were composed entirely of point masses.
Boyle's Law
Boyle's Law states that the product of the volume and pressure of a gas remains constant when the temperature stays the same. In mathematical terms, PV = kP, where P is the pressure, V is the volume of gas at constant temperature, and k is a constant.
Charles's Law
Charles's Law states that the volume of a fixed mass of an ideal gas varies directly with its absolute temperature T, as expressed by V ∝ T or PV = nRT.
Gay-Lussac's Law
Gay-Lussac's Law states that the pressure exerted on a closed container by a confined gas is directly proportional to the temperature of the gas in Kelvin; the product of the volume and pressure of such a gas is equal to a constant times the absolute temperature.
Avogadro's Law
Avogadro's Law states that volumes of two different gases are proportional to the number of moles of gas they contain, if the temperature and pressure are the same.
First Law of Thermodynamics
The First Law of Thermodynamics, also known as the Law of Conservation of Energy, states that energy cannot be created or destroyed, it can only be transferred or transformed. This means that the total energy of an isolated system remains constant.
Second Law of Thermodynamics
The Second Law of Thermodynamics states that the total entropy of a closed system always increases over time, or that the total entropy of the universe remains constant in the absence of external influences.
3 Fundamental Gas Laws
The 3 fundamental gas laws are:
- Boyle's Law: Describes the inverse relationship between the pressure of a gas and its volume, assuming constant temperature.
- Charles's Law: Describes the direct relationship between the volume of a gas and its temperature, assuming constant pressure.
- Gay-Lussac's Law: Describes the direct relationship between the pressure of a gas and its temperature, assuming constant volume.
These laws are used to predict the behavior of gases under different conditions and form the basis of understanding the thermodynamics of gases.
