How does the particle model describe solid?
The particles in a solid are held together strongly. The spaces between the particles are very small. A has a fixed shape and a fixed volume because the particles can move only a little. The particles vibrate back and forth but remain in their fixed positions.
What are characteristics of solid as per kinetic model?
The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.
What is the kinetic particle model?
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
What is the particle kinetic energy of a solid?
Solids have the lowest kinetic energy as they are tightly packed and vibrate in place. Liquids have comparatively higher kinetic energy so the particles slide past each other. Gases have the most kinetic energy as a result they float around in the air.
What best describes a solid?
Correct answer: Definite volume and definite shape. Explanation: A solid is defined as having a definite shape and definite volume. A liquid is defined as having a definite volume, but not a definite shape.
How does the particle model of matter describe solids liquids and gases?
Use the particle model of matter to explain why solids have a fixed shape, but gases fill the shape of the container they are in. Solids have a fixed shape as their particles are arranged in a regular, fixed arrangement and they have strong forces holding them together, so the shape of the solid remains fixed.
How is a solid described in terms of the kinetic molecular theory?
Solid particles do move, but not very far! Solid particles have relatively little kinetic energy and vibrate in place. Because of this, they can’t flow like liquids. Most solids are arranged in a tightly packed crystalline structure.
What are the characteristic of solid particles?
In a solid, the particles (ions, atoms or molecules) are closely packed together. The forces between particles are strong so that the particles cannot move freely but can only vibrate. As a result, a solid has a stable, definite shape, and a definite volume. Solids can only change their shape by applying force to them.
What is kinetic molecular model of liquids and solids?
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
What is the particle model of solids liquids and gases?
The particle model is a scientific theory that explains the properties of solids, liquids and gases by suggesting that all matter is made of particles, and that those particles behave differently in solids, liquids and gases.
How the kinetic molecular model of liquids and solids explain its properties?
Liquids have more kinetic energy than solids. When a substance increases in temperature, heat is being added, and its particles are gaining kinetic energy. Because of their close proximity to one another, liquid and solid particles experience intermolecular forces. These forces keep particles close together.
How do you describe solid in chemistry?
A solid is a state of matter characterized by particles arranged such that their shape and volume are relatively stable. The constituents of a solid tend to be packed together much closer than the particles in a gas or liquid.
What is the kinetic particle theory of matter?
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
What is the potential energy of a particle?
When a particle is a distance r from the origin, its potential energy is given by the equation U (r)=kr, where k is constant and r= (x^2+y^2+z^2)^1/2 A. find a mathematical expression in terms of x,y, and z for the y-component of the force on the particle
What is the kinetic model of matter?
What is the Kinetic Model of Matter? The kinetic theory is that all matter is made up of a vast number of small particles (atoms or molecules), all of which are in continuous, spontaneous movement. The idea is kinetic or kinetic molecular. The fast traveling particles collide continuously with each…
What is kinetic molecular theory used for?
The kinetic molecular theory can be used to explain the results Graham obtained when he studied the diffusion and effusion of gases. The key to this explanation is the last postulate of the kinetic theory, which assumes that the temperature of a system is proportional to the average kinetic energy of its particles and nothing else.
