7. Study of Gas Laws
The study of gas laws encompasses different laws that describe the relationships among pressure, volume, and temperature of gases. Boyle's Law highlights the inverse relationship between pressure and volume at constant temperature. Charles's Law emphasizes the direct proportionality between volume and absolute temperature at constant pressure, leading to the Combined Gas Law that merges these principles. Application of these laws spans various practical scenarios including the functioning of balloons, industrial gas management, and atmospheric studies.

What we have learnt
- Gases have no fixed shape or volume and their behavior is regulated by gas laws.
- Boyle's Law and Charles's Law illustrate fundamental relationships involving gas pressure, volume, and temperature.
- The Law of Conservation of Mass and the Law of Constant Proportions are integral principles in chemical reactions and compound formation.
Key Concepts
- -- Pressure (P)
- The force exerted by gas molecules per unit area, measured in atmospheres or Pascals.
- -- Volume (V)
- The space occupied by the gas, typically measured in liters or cubic centimeters.
- -- Temperature (T)
- A measure of thermal energy, which must be converted to Kelvin for gas law calculations.
- -- Boyle's Law
- At constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure.
- -- Charles's Law
- At constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature.
- -- Combined Gas Law
- A law that combines Boyle's and Charles's laws, relating pressure, volume, and temperature of a gas.
- -- Standard Temperature and Pressure (STP)
- Defined as 0°C (273 K) and 1 atm (760 mmHg), serving as a reference point for gas behavior.
