A chemical change is a change in the of a substance?
A chemical change is a change in which a change of matter that produces one or more new substances is a chemical change.Unlike a physical change, a chemical change produces new substances with new and different properties. Examples of chemical changes are combustion,electrolysis, oxidation,and tarnishing, frying an egg, burning of wood, cutting a tree.
Why does evaporation require that heat energy be added to a substance?
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's temperature)
What is the meaning of Physical Change What is the meaning of Chemical Change?
PHYSICAL CHANGE - refers to the change in size, shape, or state of matter. CHEMICAL CHANGE - happens when one chemical substance is transformed into one or more different substance, such as iron becomes rust.
What is a change in matter in which new or different kinds of matter are formed?
When one or more new substances is created, the change is called a chemical change. A chemical change has occurred if there is a new substance created, there was energy released or absorbed, or the substances no longer exhibit the same chemical properties.
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance it is an?
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance it is a compound.

What types of chnges converts one substances into one or more new substances?
A chemical change produces a new substance with different properties than the original substance.

Does there density of object change when there is more present?
No. Density is a characteristic property, so there it is always the same no matter how much of the substance is present.
Why does the matter expand when heated?
Heat energy causes all matter to expand, a reason for this strange occurrence is that when a particular substance receives heat whether it be through conduction, convection or radiation the atoms inside the substance become more energised therefor needing more space to move, they push the outside boundaries making the substance expand. If the substance receives an exceeding amount of heat energy it will change states of matter.
What happens to density of a substance during thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.
