Study Notes
Definition of Gas
-
State of Matter: One of the four fundamental states of matter, alongside solids, liquids, and plasma.
-
Characteristics:
- Shape and Volume: Gases do not have a fixed shape or volume; they expand to fill their container.
- Compressibility: Gases are highly compressible, meaning they can be easily pressed into smaller volumes.
- Low Density: Gases typically have much lower densities than solids and liquids.
- Molecular Arrangement: Molecules in a gas are widely spaced and move freely, allowing for high kinetic energy.
-
Behavior:
- Governed by laws such as Boyle's Law, Charles's Law, and Avogadro's Law.
- Follow the Ideal Gas Law, which relates pressure, volume, temperature, and number of moles (PV=nRT).
-
Common Examples:
- Air (a mixture primarily of nitrogen and oxygen).
- Hydrogen, oxygen, carbon dioxide, and natural gas.
Definition of Gas
- One of the four fundamental states of matter, alongside solids, liquids, and plasma.
- Gases lack a fixed shape or volume and expand to fill the container they are in.
- Highly compressible, allowing them to be easily reduced in volume through pressure.
- Typically exhibit much lower densities compared to solids and liquids.
- Molecules in gases are widely spaced and move freely, contributing to their high kinetic energy.
- The behavior of gases is governed by various laws, including Boyle's Law (pressure-volume relationship), Charles's Law (volume-temperature relationship), and Avogadro's Law (volume-amount relationship).
- The Ideal Gas Law (PV=nRT) connects pressure (P), volume (V), temperature (T), and the number of moles (n) of a gas.
- Common examples of gases include air (primarily nitrogen and oxygen), hydrogen, oxygen, carbon dioxide, and natural gas.
