When matter changes state does become a different kind of substance?
Changes of state of matter are physical processes, the molecule remain unchanged.
What kind of change occurs when a compond is separated into its components?
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.
What kind of change happens when the composition of a substance does not change?
A physical change occurs when the composition of a substance does not change. This means the substance retains its chemical identity but may undergo a change in its physical properties like shape, size, or state of matter. Examples include melting, freezing, boiling, or dissolving.
What are the properties of Substances and mixture?
PROPERTIES OF PURE SUBSTANCE & MIXTUREPURE SUBSTANCE*have homogeneous / uniform in appearance*made up of only one kind of materials*maybe simple elements*chemically combined as compoundMIXTURE*made up of 2 or more components*can be separated by physical means*maybe homogeneous or heterogeneoushope its help you- ejohnnicole@yahoo.com

How many kinds of matter are in a pure substance?
A pure substance contains only one kind of matter. It cannot be separated into other substances by physical means.

Changes of state of matter are physical processes, the molecule remain unchanged.
What kind of change occurs when a compond is separated into its components?
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.
Does a mixture contain only one kind of substance?
A mixture is multiple things mixed together - hence the name. A product with only one kind of substance is a "pure substance."
What kind of changes in substance are always physical changes?
each substance has a density that differ from the densities of other substance.
Can compounds be separated into physical or chemical properties?
I would say it depends on what kind of compound it is.
Can an element be separated into its elements using physical properties?
An element is the basic purist substance , it is composed of atoms of same kind ,not of elements hence an element can't be separated in elements , your question is wrong . A compound can be separated in component elements .
What kind of change happens when a substance dissolves?
I want to say physical change
Physical properties are altered but the substance remains the same kind of matter?
Physical properties are characteristics that can be observed or measured without changing the composition of the substance. When physical properties are altered, such as when a substance changes state (solid to liquid), the basic chemical composition remains the same, indicating that it is still the same kind of matter.
What kind of properties can be determined without changing a substance into a different substance?
physical: color, shape, texture, smell, ext.
Distinguish between a substance and a mixture and give two example of each?
A mixture, such as pizza or soft drink, is a material made up of two or more subtances that can be easily separated by physical means, but a substance has a fixed composition, it cannot be separated by physical means.
Is a cake a physical or chemical change?
Cake is a substance. It's not a "change" of any kind.
