The kinetic theory of gases explains the behavior of gas molecules using assumptions about their motion and interactions. It states that gases consist of tiny particles in constant random motion. The theory describes pressure, temperature, and volume relationships based on ...
An ideal gas follows the ideal gas law, where pressure, volume, and temperature are related. It consists of randomly moving particles with no intermolecular forces. Collisions between particles and container walls are perfectly elastic. The gas obeys Boyle’s, Charles’s, and ...
The velocity of sound in gases depends on temperature pressure and molecular composition. It is given by the formula: v = √(γ R T / M) where γ is the adiabatic index R is the gas constant T is temperature ...
Monoatomic gases consist of single atoms not bonded to others. They include noble gases like helium, neon, argon, krypton, xenon and radon. These gases are chemically inert due to their stable electron configurations. They exist in a gaseous state at ...
Kinetic theory of gases explains gas behavior using molecules in constant motion. It states that gas molecules move randomly collide elastically and obey Newton’s laws. Pressure results from collisions with container walls. Temperature is proportional to average kinetic energy. This ...
Gas molecules move freely in all directions and have high kinetic energy. They are widely spaced with weak intermolecular forces. They collide elastically with each other and container walls. Their movement depends on temperature and pressure. Gases expand to fill ...
Kinetic energy is the energy an object has due to its motion. It depends on mass and speed. Faster or heavier objects have more kinetic energy. It is calculated using the formula KE = ½ mv². Kinetic energy can be ...
An ideal gas follows the ideal gas law without interactions between molecules. It obeys Boyle’s, Charles’s, and Avogadro’s laws. Its particles move randomly in constant motion. Collisions are perfectly elastic. Temperature relates to kinetic energy. It is hypothetical and useful ...
Equilibrium refers to a state where opposing forces or processes are balanced. In thermodynamics, it occurs when a system’s properties such as pressure, temperature and volume remain constant over time. A system is in mechanical, thermal, and chemical equilibrium when ...
