Gas Pressure (Gaz basıncı)
Gaz basıncı is the force exerted by gas molecules colliding with the walls of their container. Understanding gas pressure is essential for various applications in chemistry and physics.
Key points:
- Gas pressure is exerted equally in all directions
- It increases with temperature and decreases with volume
Definition: İdeal gaz is a theoretical gas that perfectly follows the gas laws.
Gaz basıncı formülü: P = nRT / V
Where n is the number of moles, R is the gas constant, T is temperature, and V is volume.
Vocabulary: Barometer is an instrument used to measure atmospheric pressure.
Important concepts:
- Boyle's Law: Pressure and volume are inversely proportional at constant temperature
- Charles's Law: Volume and temperature are directly proportional at constant pressure
- Avogadro's Law: Volume and number of moles are directly proportional at constant temperature and pressure
Example: In a closed container, increasing the temperature will increase the gas pressure if the volume remains constant.
Gazlar yoğunluk formülü: ρ = PM / RT
Where ρ is density, P is pressure, M is molar mass, R is the gas constant, and T is temperature.
