What is the name given to the movement of the particles which causes the mixing?
The movement of particles that causes mixing is called diffusion. It is the process by which particles move from an area of high concentration to an area of low concentration, resulting in a more uniform distribution of the particles.
How many representatives particles are there in 1.45 grams of a molecular compound with a gram molecular mass of 237 grams?
To determine the number of representative particles in a sample of a molecular compound, you need to divide the given mass by its gram molecular mass, and then multiply by Avogadro's number (6.022 x 10^23 particles per mole). In this case, for 1.45 grams of a compound with a gram molecular mass of 237 grams, you would calculate (1.45 g / 237 g/mol) * 6.022 x 10^23 particles/mol to find the number of representative particles.
What happens to particles when thermal energy is given to them?
When thermal energy is given to particles, they gain kinetic energy and begin to vibrate or move more rapidly. This increase in movement causes the particles to spread out and the substance to expand, leading to a rise in temperature.
What is average kinetic energy of the particles of matter in a given space?
The average kinetic energy of particles in matter is directly related to the temperature of that matter. As temperature increases, the average kinetic energy of particles also increases. This energy is due to the random motion of particles within the substance.
Why do substance expand when heat energy is added to them?
Heat is a measurement of the amount of motion (or kinetic energy) of the particles of which a given substance is composed. In a solid, this motion is just a vibration, since the particles remain in place. When particles vibrate more, they will take up more space. In a gas, the particles move independently of each other, and if they move faster, they will exert more pressure and thus will tend to expand.
What name is given to the movement of particles like pollen grains on a surface of liquids?
The name of this movement is Brownian motion.
What is the movement of particles from regions of lower density to regions of higher density?
The movement so described is called diffusion. When particles of regions of higher density move to regions of lower density, they are said to diffuse.
What name was given to the zigzag motion of the particles?
It is called Brownian motion, after Robert Brown. See the related link below.
What is the name given to the movement of the particles which causes the mixing?
The movement of particles that causes mixing is called diffusion. It is the process by which particles move from an area of high concentration to an area of low concentration, resulting in a more uniform distribution of the particles.
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
When an object gains thermal energy, the motion of its molecules increases, leading to faster movement and higher kinetic energy. This can result in the object heating up. Conversely, when an object loses thermal energy, the motion of its molecules decreases, leading to slower movement and lower kinetic energy, resulting in the object cooling down.
What does the word diffusion mean?
Diffusion refers to the process by which particles spread out evenly in a given space due to their random movement. This occurs from an area of high concentration to an area of low concentration until equilibrium is reached. It is a fundamental principle in various scientific fields including physics, chemistry, and biology.

Which term is defined as a measure of the energy of motion of particles in a substance?
Heat is a measure of the amount of energy due to the motion of the particles in a gas, liquid, or solid. Temperature is a measure of the average amount of heat energy in a given body.
What does diffusion get its energy from?
Diffusion does not require energy input because it is a passive process. It is driven by the random motion of particles and the tendency of particles to move from areas of higher concentration to areas of lower concentration.
What is average kinetic energy?
Energy of movement ; particles that make up all matter have kinetic energy
What is it called when waves moves through a given point over time?
Wave motion is the term used to describe the movement of waves through a specific point over time. This motion involves the transfer of energy from one point to another through the vibrations of particles in a medium or through the propagation of electromagnetic fields in space.
What does the word kinetic realate to?
Anything Kinetic is associated with movement (eg. Kinetic energy is often given off by vibrations and general movement.)
