- Melting of ice to form water is a physical change in matter as the substance changes from solid to liquid state without altering its chemical composition.
- Combustion of wood to produce ash, heat, and light is a chemical change in matter as the wood undergoes a chemical reaction to form new substances.

What are the two changes of state in matter?
"The" two changes are wrong. There are lots of different states of matter, and therefore many different possible transitions. The most commonly studied states of matter are solid, liquid, and gas; each of them can change directly to each of the others, for a total of 6 types of change.
Are changes in the state of matter are physical chemical or neither?
Changes in the state of matter are physical because they involve a change in the physical properties of a substance, such as its shape, volume, or density, without altering its chemical composition. Examples include melting, freezing, evaporation, and condensation.
What are 3 examples of matter and 3 non examples of matter?
Examples of matter: water, air, iron. Non-examples of matter: light, sound, thoughts.
When matter changes how it looks but not what it is made of?
It is a physical change.
What are two examples of things that are not matter?
Gravity: because you cant see or feel it. light: light is given off and we see it. these can't be put in a jar.
What are examples of a chemical change in matter?
Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
What are two examples for each of the state's of matter?
state two examples for each of the four states of matter
What are examples of chemistry?
The study of matter and changes in matter best described the science chemistry.
What are the two examples for each of the four states of matter?
state two examples for each of the four states of matter
What does changes in matter mean?
Examples are: freezing, liquefaction, sublimation, boiling.
What are examples of expansions and contractions of matter?
Examples of expansions of matter include the increase in volume of a gas when heated and the expansion of a metal strip in response to temperature changes. Examples of contractions of matter include the shrinking of a balloon when the gas inside cools down and the contraction of a metal wire when it is cooled.
What are examples for reversible matter?
Examples of reversible matter include water (liquid to solid state), melting ice (solid to liquid), and evaporating alcohol (liquid to gas). These examples involve phase changes where the matter can easily transition back and forth between states without undergoing any permanent chemical changes.
What happens when matter is changed physically?
It means that although it changes, no new substances are formed. Examples of such changes are melting and other state changes, and dissolving.
What are some examples of a chemical change in matter?
Examples of chemical changes in matter include burning wood (combustion), rusting of iron, cooking an egg, and fermenting grapes to make wine. These processes involve the rearrangement of atoms in the substances, resulting in the formation of new chemical compounds with different properties.
What are some examples of physical changes that involoved color?
melting candle wax it changes from a non clear to a clear form of matter
What are the two changes of matter give 3 examples about the two changes of matter?
the change of matter are the physical and chemical change physical change is a substance that do not change. chemicalchange is a substance that change. examples of physical: crumpling of paper evaporation of liquid examples of chemical: digestion of food burning of wood
What factors affect the changes of matter?
Factors that affect the changes of matter include temperature, pressure, and the presence of catalysts. Changes in these factors can lead to physical changes, such as melting or boiling, as well as chemical changes, such as reactions that form new substances. The composition and properties of the matter can also influence how it changes under different conditions.
