LaoTo 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.
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.
