Why is salt water a physical separation?
Salt water is a physical separation because the salt dissolves in the water, creating a homogeneous mixture. The salt molecules do not chemically combine with the water molecules and can be separated through physical means, such as evaporation or filtration.
When water evaporates is oxygen emitted?
No. Evaporation is when water liquid changes to water vapor. In the vapor there are still water molecules. The only sense in which there is separation is that water molecules are on average much closer together in the liquid phase than in the gas phase.
In which of the three states do the water particles have greatest average separation?
In the three states of matter—solid, liquid, and gas—water particles have the greatest average separation in the gas state. In gases, particles are far apart and move freely, resulting in minimal intermolecular forces. In contrast, in solids, water molecules are tightly packed in a fixed structure, while in liquids, they are closer together but still have some mobility.
What is the separation of particles as heat is added which causes an increase in the size of the substance?
Whenever heat is added to the system, we increase the average kinetic energy of molecules. Increasing the K.E. of molecules cause the molecules to move further apart and collide back even more violently. This can cause size of the substance to increase.
The average kinetic energy of gas molecules increases with temperature true or not?
temperature is the measure of a molecule's average kinetic energy, so yes.
How do molecular sieves work to separate molecules based on size and shape?
Molecular sieves work by trapping molecules that are too large to pass through their pores, while allowing smaller molecules to pass through. This separation is based on the size and shape of the molecules, with larger molecules being excluded from passing through the sieve.
Why does metal contract?
Metals, like most solids will contract when cooled. When cooled the atoms or molecules slow down, vibrating less often, causing a smaller average separation between them.

What does the experiment suggest about the average speed of hydrogen molecules compared with the average speed of molecules in the air?
The experiment suggests that the average speed of hydrogen molecules is higher than the average speed of molecules in the air. This is because hydrogen molecules are lighter and have a higher root mean square speed due to their lower mass.

What are some separation variables with the molecules in electrophoresis?
hi. i dont know the question. ok bye.
What does dialysis separate?
the separation of disolved molecules based on their ability to pass through a semipermeable membrane.
What is a measure of the average of motion of molecular?
The measure of the average motion of molecules is temperature. Temperature is a reflection of the average kinetic energy of the molecules in a substance.
What is a measure of the average amount of motion molecules?
The average amount of motion of molecules in a substance is measured by temperature. Higher temperatures indicate that the molecules are moving faster on average, while lower temperatures indicate slower average motion.
How does myosis work?
the division or separation of cells
