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.
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.
Average amount of energy of motion in the molecules of a substance?
The average amount of energy of motion in the molecules of a substance is known as the substance's temperature. This energy is measured in units of kinetic energy. The higher the temperature, the greater the average energy of motion in the molecules.
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.

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.
What is the work of purifier?
gravity separation
How does myosis work?
the division or separation of cells
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.
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.
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 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.
Characteristics for polar and nonpolar molecues?
Polar molecules have separation of charges .ie. they have a partial positive and partial negative charges on molecule as in water . Non polar molecules e.g.methane has no separation of positive and negative charges as difference of electronegativity in C and H is very small .
