What else can I help you with?
For diffusion to occur which condition must be met?
Diffusion occurs when a substance moves from an area of high concentration to an area of low concentration. This will happen naturarally without disruption, But is more common (and will happen faster) in a warm environment.
What if you mix matter with another substance?
What happens would depend on what sort of matter you are stirring in.
What is called changing a particular substance into another particular substance?
The conversion of one substance to another substance is a chemical change, which happens as a result of a chemical reaction.
If you place a less dense substance into another substance with a greater density what happens?
It floats.
Where in animals does diffusion take place?
Diffusion happens in every plant and animal cell. It occurs through the membrane of each and every cell in the organism.
How solution forms?
solutions are formed by adding another substance to another substance when this happens it is now called "solution"
What happens when you dilute a substance?
Concentration of acid will decreases on dilution. Concentration means amount of 1 substance per unit amount of another substance in which 1st substance is dissolved or mixed. So if u increase the solvent( 2nd substance) i.e., on dilution, then the ratio '1st substance per unit 2nd substance' decreases. Hence concentration decreases.
What happens to light rays when it passes from one substance to another?
When light passes from one substance to another, its speed changes causing the light ray to bend or refract at the boundary between the two substances. The amount of bending depends on the difference in the optical properties of the two substances, such as their refractive indices.
Change 3 explain what happens to the identity of a substance in a physical change 4- explain what causes a substance to change from one state to another 5- explan what happens to particle size?

During the process of diffusion what is occurring?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration. This happens naturally as particles move randomly and collide with each other, eventually distributing themselves evenly throughout the space.
What happens to the atom in substance after a chemical reaction?
Nothing, it just bonds with another atom, radical.
When a solution is?
when no more solute will dissolve ========== when the concentration of the solute is equal to the concentration that would be in equilibrium with any solid of the same substance - when that happens, no more solute will dissolve, or more precisely, if any more dissolves, it would be expected to cause the same amount to precipitate out, thus keeping the concentration constant.
