Kinetic Theory.
According to the kinetic theory of gases, gas particles are in constant random motion due to their kinetic energy. This theory also explains how gas pressure and temperature are related to the average kinetic energy of the gas particles.
The kinetic theory states that the particles in matter are always in constant random motion. This motion increases with temperature, causing the particles to spread apart and occupy more space. This explains the behavior of gases, liquids, and solids at a molecular level.
Gases behave differently at different pressures and temperatures. At low pressures, gases expand to fill the available space. At high pressures, gases become more compact. At low temperatures, gases condense into liquids or solids. At high temperatures, gases expand and exert greater pressure.
This is describing the concept of kinetic molecular theory, which explains the behavior of particles in matter. In gases, particles are in constant motion and tend to move freely without sticking together. This results in gases taking the shape and volume of their container.
Well I'm not exactly sure of what you're asking but molecules behavior is determined by the amount of energy/heat, high amounts of energy results in weaker bonds thus the molecules move farther apart. i.e solids have low amounts of energy so the bonds between the molecules are stronger thus a solid shape where as in gases there's a higher amount of energy thus a weaker bond therefore the molecules are spread put allowing gases to easily take on the shape of it's container. this was simply particle theory and i apologize if this didn't clear anything up
Kinetic Theory.
Kinetic theory is a model that explains how gases behave on a microscopic level. It states that gases are comprised of small particles (such as atoms or molecules) that are in constant motion, colliding with each other and the walls of their container. This motion is what produces the macroscopic properties we observe, like pressure and temperature.
In a solid, particles are closely packed together and vibrate in fixed positions. They have a fixed shape and volume, and only have slight movements. The particles do not have enough energy to move around freely like in liquids or gases.
At absolute zero, gases have minimal thermal energy and thus minimal motion of gas particles. This results in gases being in a state of maximum order, with particles coming to a complete stop. The gas would essentially behave as if it were in a solid state.
The behavior of particles in matter is described by the field of physics known as quantum mechanics. Quantum mechanics explains how particles such as atoms, electrons, and protons interact and behave at the subatomic level. The theory addresses concepts like wave-particle duality, uncertainty principle, and quantum entanglement to explain these behaviors.
The particles are moving rapidly
In chemistry, KMT stands for Kinetic Molecular Theory. It is a theory that explains the behavior of gases in terms of the motion of their particles. It states that gases are made up of a large number of small particles that are in constant, random motion.
Two gases on the periodic table that behave like ideal gases are helium (He) and neon (Ne). Ideal gases follow the ideal gas law, which assumes that the gas particles are point masses and do not interact with each other. Helium and neon have low atomic masses and weak intermolecular forces, making their behavior close to ideal in most conditions.
Gases - force of attraction is very weak - the particles in gases have a lot of space in between them - move very freely - gases are the least dense (from solids and liquids) - particles in gases are very "excited" and move around a lot.
The name of the theory that explains Brown's observation is the kinetic molecular theory of matter. This theory states that all matter is composed of particles (atoms or molecules) that are in constant motion, and explains the behavior of gases, including diffusion, pressure, and temperature.
is it true the space between gas particles becomes very large
Atoms and molecules are always moving or vibrating.
