Diffusion. Diffusion is a passive process, meaning that it requires no energy input from a cell or other source, other than the energy of motion that all substances have above absolute zero (0o Kelvin).

Molecules are not in random motion when that substance is at?

Molecules are not in random motion when a substance is at absolute zero, the lowest possible temperature at which molecular motion ceases. At this point, molecular movement only exists due to the zero-point energy, preventing complete immobilization.


What is the thermal energy of a substance?

Thermal energy of a substance is the internal energy associated with the random motion of its atoms and molecules. It is a measure of the total kinetic energy of the particles within the substance.


How do you describe the dissolving process as a result of random molecular motion?

In the dissolving process, the solute particles break apart and disperse into the solvent due to the random motion of molecules. This motion causes collisions between solute and solvent molecules, leading to a gradual mixing at the molecular level until the solute is evenly distributed throughout the solvent.


When a substace is heated how does the molecular motion change?

When a substance is heated, the molecules within it absorb energy and increase their kinetic energy, causing them to move more rapidly. This increased molecular motion leads to increased collisions between molecules and a higher overall temperature of the substance.


What is the random molecular of a substance is greatest when the substance is?

In a gaseous state, as the molecules have the highest degree of freedom to move around and exhibit random motion. This leads to greater randomness in the distribution of molecular positions and velocities, resulting in a higher entropy compared to when the substance is in a liquid or solid state.


What term describes the disorder of random molecular motion?

Brownian motion describes the disorder of random molecular motion, which is caused by the collision of molecules in a fluid. This phenomenon was first observed by botanist Robert Brown in 1827.


What term describes the disorder of random moleculer motion?

Brownian motion describes the disorder of random molecular motion. It is the random movement of particles in a fluid or gas due to their collisions with other particles.


What is random molecular motion?

Random molecular motion refers to the constant, unpredictable movement of molecules due to their thermal energy. This motion occurs in all substances, and the speed and direction of the molecules change rapidly as they collide with each other and their surroundings. It is this random motion that contributes to various macroscopic properties of matter, such as diffusion and viscosity.


Which term describes the describes the disorder of random molecular motion?

entropy


Molecule of a substance are in a motion?

Molecules of a substance are in constant motion. Whether you have a solid, liquid, or gas, the particles are moving (but the speed and amount they move differs). Particles of a solid move the least (they basically vibrate), particles of a liquid can flow around one another, and particles of a gas have a lot of space between them because they move in random, constant motions.


Difference between molecular motion and diffusion?

It triggers diffusion because diffusion is the movement of molecules, therefore as soon as the molecules move diffusion begins to do it's job. It will take them from areas of greater concentration to areas of lesser concentration.


Is molecular motion ordered and predictable?

No, molecular motion is generally random and chaotic. While certain patterns of motion can be observed in larger systems, such as in crystal structures, on a molecular level, individual molecules move in unpredictable ways due to constant collisions and interactions with other molecules.
