simply all particles of one substance are identical means just that. all of the particles that make up a piece of matter are the same. an example of this is water. if you look at water under a microscope, you will see that all of the particles that make up the water are identical.

Is 1 mole of particles a very large number of particles or a very small number?
1 mole of representative particles of a substance is a very large number. It represents 6.02294x1023 particles.
How many particles are in 1 mole of carbon?
Number of particles = number of mol x avogadro constant = 1 x 6.02 x 1023
What does foreign substance mean?
A foreign substance is some substance or material that does not belong where it is, such as a rock in your cereal.
What does Pure Substance mean in science?
I substance that made of only one element, to make a substance.
What does diffusion mean?
Where there are two (or more) substances in contact, diffusion happens as particles of one substance move from an area where there are a lot of those particles to an area where there are fewer of those particles. The process can happen in the gas, liquid and solid phase. Note, diffusion is driven by random movement of the particles not by mechanical mixing, the phase of the system will therefore largely determine the rate of diffusion. The term is also used in a more abstract manner to describe spreading of something more widely. The movement of a substance from a region of high concentration into a region of low concentration is called diffusion.
What does an Avogadro's number of a substance is called a mole mean?
It is the number of particles in a mole of any substance
How is the kinetic energy of the particles that make up a substance different after it changes?
If you mean by heating it... When you heat a substance, the thermal energy of its particles increases. This means that the particles will move around faster as they have a higher kinetic energy.
Is 1 mole of particles a very large number of particles or a very small number?
1 mole of representative particles of a substance is a very large number. It represents 6.02294x1023 particles.
What increases the temperature of a substance?
The temperature of a substance increases as the mean random kinetic energy of its particles increases. This is because temperature of an object is directly proportional to the kinetic energy of its particles. Thus when the particles move faster as a whole, such as when the object is put near a flame, the object heats up.
What does the name Vapour mean?
a visible suspension in the air of particles of some substance. in other words, a substance in the gaseous state (a gas state) and then distinguished from the liquid or solid state.
Are water particles really water molecules?
If you mean the smallest particle of water that has the properties of water, then yes, water particles are molecules.
When the temperature of a substance decreases increases what happens?
The temperature of a substance increases as the mean random kinetic energy of its particles increases. This is because temperature of an object is directly proportional to the kinetic energy of its particles. Thus when the particles move faster as a whole, such as when the object is put near a flame, the object heats up.
What does expand mean in chemistry?
an increase in the volume of a substance while its mass remains the same . expansion is usually takes place due to increase in temperature , when substance is heated the molecular bond between the particles are weakened , the particles move faster, causing the substance to expand
Are the particles in a liquid all the same?
If you mean the smallest particle of water that has the properties of water, then yes, water particles are molecules.
How do you open a halfway house for substance abusers?

What identical mean?
identities mean who you are
A substance changes from a solid to a liquid?
You mean if a substance can go from solid to liquid? Of course, take the ice cubes out of the freezer and you'll see it happening. Do you mean that when such process occurs, does the substance changes? No, only the grouping and movement of particles in it.
