To work out the average separation of molecules, you would first need to measure the distances between individual molecules in a given sample. Then, you would sum up all these distances and divide by the total number of distances measured to calculate the average separation. This value gives you an idea of the average distance between molecules in the sample.

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?
The separation of particles as heat is added, causing an increase in the size of the substance, is known as thermal expansion. This phenomenon occurs because the increased thermal energy causes the particles to move more vigorously, leading to greater distances between them and an overall expansion of the material.
The average kinetic energy of gas molecules increases with temperature true or not?
True. As temperature increases, the average kinetic energy of gas molecules also increases. This is because temperature is a measure of the average kinetic energy of the molecules in a substance.
How does molecules affect the separation between pepper water and dish detergent when it is mixed?
by taking a fat dump on your computer and jumping in a lake
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 is the work of purifier?
gravity separation

What does dialysis separate?
the separation of disolved molecules based on their ability to pass through a semipermeable membrane.
What are some separation variables with the molecules in electrophoresis?
hi. i dont know the question. ok bye.
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.
How does myosis work?
the division or separation of cells
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 .
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.
Two examples of separation by loading?
Chromatography involves separation by loading a sample onto a stationary phase, such as a column packed with beads. As the sample flows through the column, components interact differently with the stationary phase, leading to their separation. Electrophoresis is another example, where molecules are separated by loading them onto a gel matrix and subjecting them to an electric field. The movement of molecules through the gel is influenced by their size and charge, allowing for separation based on these characteristics.
