What transfer of thermal energy by collisions between particles in matter?
Convection
Heat is transferred from one particle of matter to another without the movement of matter itself in what process?
Conduction is the process by which heat is transferred between particles of matter without any movement of the matter itself. This occurs when particles vibrate and transfer their kinetic energy to neighboring particles. It is most efficient in solids due to their closely packed arrangement of particles.
What is the release of light energy by particles of matter that have absorbed energy?
"phosphorescence"Scattering is the release of light energy by particles of matter that have absorbed energy. The transfer of energy carried by light waves to particles of matter is absorption.
Which is associated with weak light rays that travel in the different directions?
Scattering is associated with weak light rays that travel in different directions. This phenomenon occurs when light interacts with particles or medium that causes it to deviate from a straight path, resulting in the light being diffused in various directions.
The scattering of light caused by small suspended particles?
This scattering of light by small particles is known as the Tyndall effect. It occurs when light strikes particles in a medium, causing the light to scatter in different directions, making the beam visible. This effect is commonly observed in colloids, dust particles in the air, or fog.
When radiation occurs?
Radiation occurs whenever something spreads out along the radii of the system. [You see where the word comes from.] Sound radiates, as does heat and light.Atomic radiation, or radioactivity also radiates out in all directions. Unless otherwise constrained. It occurs when a disintegration occurs within the nucleus of an atom.Radiation also occurs with populations of plants and animals. When introduced into a new environment, a species is said to radiate as it spreads out.
In optics the transfer of light energy to particles of matter is called?
In optics, the transfer of light energy to particles of matter is called absorption. This occurs when the photons of light are absorbed by the particles, resulting in an increase in the particles' energy level.
When a smell spreads the particles move away from where they are relatively of them?
When a smell spreads, the particles responsible for the scent disperse from their source into the surrounding air. This movement occurs due to diffusion, where particles move from an area of higher concentration to areas of lower concentration. As a result, the smell can travel and become detectable at distances away from the original source. This process continues until the scent is evenly distributed in the environment.
Explain why diffusion is evidence for particle models?
Diffusion occurs because particles move randomly in all directions until they are evenly distributed. This can be explained by the particle model, which states that matter is made up of tiny particles that are constantly in motion. The movement of particles in diffusion supports the idea that substances are composed of particles that are constantly moving.
What transfer of thermal energy by collisions between particles in matter?
Convection
Are the particles of gas free to move quickly in all directions?
Yes, the particles of a gas are free to move quickly in all directions. This random motion occurs due to the high kinetic energy of gas particles, which allows them to overcome intermolecular forces. As a result, gas particles spread out to fill the volume of their container, leading to the characteristic properties of gases such as low density and high compressibility.
What occurs when particles and gases in the atmosphere disperse in all directions?
When particles and gases in the atmosphere disperse in all directions, a process known as diffusion occurs. This leads to the even distribution of substances, resulting in a homogeneous mixture of gases and particles. As a result, concentrations of pollutants or other atmospheric components decrease over time, contributing to air quality and influencing weather patterns. This dispersion is influenced by factors such as temperature, wind, and atmospheric pressure.
What is the release of energy by particles of matter that have absorbed energy called?
The release of energy by particles of matter that have absorbed energy is called emission. This occurs when the particles return to a lower energy state, releasing energy in the form of light or heat.
Heat is transferred from one particle of matter to another without the movement of matter itself in what process?
Conduction is the process by which heat is transferred between particles of matter without any movement of the matter itself. This occurs when particles vibrate and transfer their kinetic energy to neighboring particles. It is most efficient in solids due to their closely packed arrangement of particles.

"phosphorescence"Scattering is the release of light energy by particles of matter that have absorbed energy. The transfer of energy carried by light waves to particles of matter is absorption.
How do particles move in the ground when an earthquake occurs?
During an earthquake, particles in the ground move in a wave-like motion due to the release of energy from the shifting of tectonic plates. This causes the ground to shake, creating seismic waves that propagate through the Earth. The particles move both horizontally and vertically, resulting in the ground shaking in different directions.
Which is associated with weak light rays that travel in the different directions?
Scattering is associated with weak light rays that travel in different directions. This phenomenon occurs when light interacts with particles or medium that causes it to deviate from a straight path, resulting in the light being diffused in various directions.
