Which is not assumption about particles in a gas according to the kinetic theory?
One assumption of the kinetic theory of gases is that gas particles occupy a negligible volume compared to the volume of the container. Therefore, the idea that gas particles have significant volume or that they interact through forces that significantly affect their motion would not align with the assumptions of the kinetic theory. Additionally, the assumption that gas particles are in constant random motion contradicts any notion of them being at rest or having fixed positions.
How does tyndall effect brownian motion?
The Tyndall effect is the scattering of light by colloidal particles in a colloidal suspension. Brownian motion is the random movement of particles in a fluid due to collisions with molecules. Brownian motion can enhance the Tyndall effect by causing the colloidal particles to move randomly, increasing the likelihood of light being scattered by the particles in different directions.
What are the consistent with the kinetic molecular theory of gases?
The kinetic molecular theory of gases posits that gas consists of a large number of particles in constant, random motion, with collisions between them being elastic. It suggests that the volume of individual gas particles is negligible compared to the volume of the container, and that the average kinetic energy of the gas particles is directly proportional to the temperature of the gas in Kelvin. Additionally, it assumes there are no intermolecular forces acting between particles except during collisions. This theory explains gas behaviors, such as pressure and temperature relationships, in terms of particle motion and energy.
How does the particles of gases affect one another's motion?
In gases, particles move freely and collide with each other and the walls of their container. These collisions are elastic, meaning that kinetic energy is conserved, and they occur without significant interactions between the particles beyond the point of collision. The random motion and spacing of gas particles result in minimal influence on each other's paths, leading to the overall behavior of gases being described by laws of probability and thermodynamics. As a result, the motion of individual gas particles is largely independent, though collective behavior can be observed in terms of pressure and temperature.
Why did smoke particles move in air?
Smoke particles move in air due to air currents, also known as convection. The warm air rises, taking the smoke particles along with it. Once the warm air cools down, the smoke particles disperse throughout the surrounding air.
Why is the kinetic model of matter called kinetic?
The kinetic model of matter is called kinetic because it focuses on the motion of particles in a substance. It explains how particles are in constant motion, with different states of matter being determined by the speed and arrangement of these particles.
Does the constant motion of the particles in a liquid cause the liquid to take the shape of its container?
Yes, the constant motion of particles in a liquid allows it to flow and take the shape of its container. This is because the particles have enough kinetic energy to move around and fill the available space.

Which observation most clearly supports the inference that liquids are composed of small particles in the motion?
"Brownian motion" is the seemingly random motion of particles. Small particles, suspended in water, seem to drift and jerk around randomly. Why should they do this? The most obvious explanation is that they are being constantly bombarded by even smaller particles: those that make up the liquid itself.

Why horizontal motion is constant?
Horizontal motion is constant when there are no external forces acting on an object in that direction. According to Newton's first law of motion, an object in motion will stay in motion at a constant velocity unless acted upon by an external force. This is why horizontal motion can remain constant when there is no acceleration or deceleration.
Why is there a haphazard motion of smoke particles seen in a smoke cell which is viewed through a microscope?
It's called Brownian motion. It's caused by atoms and molecule zipping about (because of the energy they have as a result of being warm) colliding with the smoke particles and bumping them around. It would happen less if the smoke was very cold because the atoms and molecules would move less. Conversely, if you increased the temperature of the smoke the motion would be greater

What is the particle model of matter and how does it explain the changes of state that occur with variations in temperature or pressure?
The particle model of matter describes matter as being made up of tiny particles (atoms and molecules) that are in constant motion. Changes in temperature or pressure affect the motion of these particles. With an increase in temperature, the particles move faster, leading to a change in state (e.g., solid to liquid to gas). Changes in pressure can also affect the arrangement and movement of particles, causing changes in state.
What is Tests for Persistent Directionality?
Random Walk: Evolutionary model in which changes in a trait value are conceived as being drawn at random from a constant statistical distribution of evolutionary steps.
