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?
Physical changes, such as the change from ice to water to steam; the compound remains as H2O in all three states.
What are the properties of pure substance 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

What kind of changes in substance are always physical changes?
each substance has a density that differ from the densities of other substance.
What kind of change occurs with no new substance being formed?
physical changes
Can compounds be separated into physical or chemical properties?
I would say it depends on what kind of compound it is.
What kind of change happens when the composition of a substance does not change?
Physical changes, such as the change from ice to water to steam; the compound remains as H2O in all three states.
Physical properties are altered but the substance remains the same kind of matter?
Melting ice to get water, or boiling water to get steam, doesn't change the identity of H2O.
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.
What kind of change happens when a substance dissolves?
I want to say physical change
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 properties can be determined without changing a substance into a different substance?
physical: color, shape, texture, smell, ext.
