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.
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 will not change the state of matter?
Factors such as the amount of a substance, its chemical composition, and the presence of impurities will not change its state of matter. For instance, heating or cooling a substance can change its state (e.g., solid to liquid), but simply having more or less of the same substance at the same temperature and pressure will not alter its state. Additionally, the state of matter remains unchanged as long as the temperature and pressure conditions stay constant.
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. A compound is a substance composed of two or more elements chemically bonded together in a fixed ratio.
Is wood decomposing a physical or chemical change?
The rotting of wood is a chemical change because of many reasons. One of the reasons is because when wood rots, it produces mold, which is a new substance. The definition of chemical change is a change that produces one or more new substances. When the wood rots, you are unable to take the rotted wood and mold and make it back into wood that is yet to be rotted. So because the wood produces one (or more) new substances, the rotting of wood is a chemical change.

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.

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. A compound is a substance composed of two or more elements chemically bonded together in a fixed ratio.
During thermal expansion what happens to the density of a substance?
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.
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 is a substance whose matter is more tightly packed than other another substance have a greater density or mass?
A substance with matter that is more tightly packed will generally have a greater density compared to a substance with less tightly packed matter. Density is a measure of mass per unit volume, so substances with denser matter will have more mass in a given volume.
What happens to the density of the 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.
A change that produces one or more new substances?
a chemical change
What happens when energy is taken away from matter?
The substance's particals will start slowing down and come closer together. As kinetic energy is removed from a substance, it will do the opposite as when kinetic energy is added to a substance.
