Molecules are not in random motion when that substance is at?
Absolute Zero
Brownian motion is evidence of?
random motion of molecules
What are molecules in a gas?
In random motion.
What motion of molecules of matter are always busy?
never ending random
What Diffusion?
the mixing of gas molecules due to random motion-apex
Molecules are not in random motion when that substance is at?
Absolute Zero
Average amount of energy in motion in the molecules of a substance?
The average amount of energy in the motion of the molecules of a substance is the temperature of that substance. Heat is simply random motion on a sub-microscopic scale.
The energy associated with the random motion of molecules or atoms within a substance is?
Thermal energy
How do you describe the dissolving process as a result of random molecular motion?
Dissolving is when a substance has mixed into a solvent.
Brownian motion is evidence of?
random motion of molecules
The motion of two substances by the random motion of molecules is called?
Brownian motion
What Brownian motion is evidence of?
Brownian motion is evidence of random motion of molecules.
What are molecules in a gas?
In random motion.
What do paricales do in a fluid?
Fluid means capable of flowing. So liquids and gases are considered as fluids. Particles are different from fluid molecules. Molecules will be at random motion. Only at 0 K, molecules would come to rest. Otherwise at room temperature they are at random motion. So any particle within fluid will be bombarded by these molecules and so particles too will be in random motion. This motion is termed as Brownian motion.
What is the movement of molecules as they are heated unevenly called?
Random Motion
Are the molecules in a gas in constant motion?
Yes, the molecules of a gas are constantly in a random motion if the gas temperature is more than 0 degree kelvin. This random motion determines the average kinetic energy of the molecules which is equal to the temperature of the gas. I hope this answers your question.
The first scientist to observe evidence of the random motion of molecules was?
It was Brown. They named it Brownian motion after her.
