Which tool can be used to quickly separate a dry mixture containing particles of different sizes?
A sieve or a sieve shaker can be used to quickly separate a dry mixture containing particles of different sizes. The mixture is poured onto the sieve, which allows smaller particles to fall through while larger particles are retained on top.
What is the general name for a pure substance containing different atoms chemically joined together?
A general name for a pure substance containing different atoms chemically joined together is a compound. Compounds are formed when atoms of different elements bond together through chemical reactions to create a new substance with unique properties.
Is the particles of a pure substance different?
No, the particles of a pure substance are all the same kind. In a pure substance, such as an element or a compound, the particles are identical in their chemical makeup. This is what distinguishes a pure substance from a mixture, where different substances can be present in varying proportions.
What happens to the particles when the substance changes shape?
When a substance changes shape, the particles themselves do not change. They simply rearrange their positions relative to each other. In solids, the particles vibrate and shift slightly closer or farther apart. In liquids and gases, the particles move more freely and take the shape of their container.
How many particles does the SI unit for the number of particles present?
The SI unit for the amount of substance is the mole, which is defined as containing exactly 6.022 x 10²³ particles. This number, known as Avogadro's number, represents the number of atoms, molecules, or other entities in one mole of a substance. Thus, one mole corresponds to approximately 6.022 x 10²³ individual particles.
What is a mixture and how is it different from a compound?
a compound is a substance containing 2 or more different types of elements while a mixture is a substance containing 2 or more different materials. ------------------------------------------------------------------ The components of a compound can not be separated by physical means, the components of a mixture can be separated by physical means.

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 the particles of a pure substance different?
No, the particles of a pure substance are all the same kind. In a pure substance, such as an element or a compound, the particles are identical in their chemical makeup. This is what distinguishes a pure substance from a mixture, where different substances can be present in varying proportions.
What do we call a substance containing atoms of different elements in definite fixed ratios that are bonded together?
This statement might be a good definition of a chemical compound.
What happens to the particles when the substance changes shape?
When a substance changes shape, the particles themselves do not change. They simply rearrange their positions relative to each other. In solids, the particles vibrate and shift slightly closer or farther apart. In liquids and gases, the particles move more freely and take the shape of their container.
What is a substance containing all of the same type of adom?
what is a substance containing all of the same type of atom
Are particles some kind of energy instead of substance?
yes.because particles behave as wave in sometimes.the reason is natural condition will affects on it.these also emits radiation due to containing electrons and other carriers.
What is a measure of the average energy of the particles in a substance?
Temperature is a measure of the average energy of the particles in a substance. It indicates how fast the particles are moving within the substance.
