Understanding Potential Temperature, Vapor Pressure, and Latent Heat
Potential Temperature
The equation relating temperature and pressure for an adiabatic process is known as the Poisson equation: T0 / T = (p0 / p)R / Cp
From the Poisson equation, considering that if p0 = 1000 hPa, then T0 = Θ as: Θ = T (1000 / p)R / Cp, where Θ is defined as the potential temperature.
Potential Temperature: The temperature a mass of air would acquire if it is carried through adiabatic compression or expansion (i.e., if the air mass moves up or down) to the pressure level of 1000

Tracers
Radioisotopes are used as tracers in various applications, including:
- Medical diagnostics: Tracers are used to investigate a patient’s body without surgery. Beta or gamma emitters, such as Technetium-99 and Iodine-123 (used to investigate the thyroid gland), are commonly employed.
- Environmental monitoring: Tracers help track the dispersal of waste materials.
- Industrial applications: Tracers can locate leaks or blockages in underground pipes.
Smoke Alarms
Many smoke detectors contain Americium-

Chemical Reaction Rates
The speed of a chemical process is defined as the change in the concentration of reactants or products with respect to time. The overall order of a reaction is the sum of the partial orders for each of the reagents.
Zero-Order Reactions
In these reactions, the reaction rate is independent of the concentration. Zero-order reactions are often found in heterogeneous catalysis, when the reaction is carried out on a surface saturated with reagent, and in reactions catalyzed by a

Limiting and Excess Reactants
Limiting Reactant: The reactant in a chemical reaction that limits the amount of product that can be formed. The reaction will stop when all of the limiting reactant is consumed.
Excess Reactant: The reactant in a chemical reaction that remains when a reaction stops when the limiting reactant is completely consumed. The excess reactant remains because there is nothing with which it can react.
Molecular and Empirical Formulas
Molecular Formula: The molecular formula is the
