Is sugar dissolves in hot water a chemical change or physical change?
The dissolving of sugar in hot water is a physical change because it does not alter the chemical composition of either the sugar or the water. The sugar molecules are merely dispersed throughout the water molecules.
Is dissolution of common salt is chemical or physical change?
It is a physical process; on the other hand dissociation in water is a chemical process.
What are the indicators of physacal change?
Indicators of physical change include alterations in shape, size, or state of matter without changing the substance's chemical composition. Common examples are melting, freezing, boiling, and dissolving. Physical changes are often reversible, such as ice melting into water and then refreezing. Additionally, physical changes may be observed through changes in texture or color, without any new substances being formed.
What are the characteristic of physical change?
Some common characteristics of physical changes are change in texture, change in shape, and change in state. There can also be a change in temperature and a change in color, but these are also common characteristics of chemical changes. A physical change does not change the composition of the original substance.
What is physical chage?
A physical change refers to a change in the appearance or state of a substance without altering its chemical composition. Common examples include changes in shape, size, or state of matter (solid, liquid, gas) without forming new substances. Physical changes are often reversible.

What does physical and chemical change have in common?
A physical change to an object is a change in properties not involving the chemical makeup. In other words, a physical change is any change you can make to an object without changing the actual substance. (I.e. state of matter, size, shape, color . . .etc.) A chemical change is a change that forms a new substance through a chemical reaction. A chemical reaction is often signaled by bubbling or fizzing, but the only real way to prove a chemical reaction is by coming up with a new substance. So physical changes leave you with the same substance (slightly altered in appearance/texture etc.), but chemical reactions give you a new substance.
Is melting butter a chemical change?
Partly physical, partly chemical. Melted butter has different chemical properties than solid butter. The melting process, as with chocolate, is not reversible. Proteins in the butter can become denatured, and isomerization of lipids to trans fats occurs. Phase change is a common example of physical change, but chemical change also occurs in this case.
Is splitting water through electrolysis into O2 and H2 gasses a physical or chemical change?
In a way it is both physical and chemical, because a chemical change is changing how the molecule is "built," while a physical change is the transformation from one form to the other. I would consider splitting water through electrolysis as a chemical change at first because physical change is keeping the build of a molecule the same while it's form changes. You could also say that the splitting itself occurs first, meaning chemical change first occurs. Physical change would the occur later because the points of physical forms change based on the atom or molecule. The time difference in which occurs first would be very hard to measure, down to nanoseconds, but according to common scientific sense chemical change would occur first. The true answer to this question would be that it is chemical change, because you wanted to know what the splitting part was. Hope this helps!
Is bubbles fizzing a physical or chemical change?
Physical. If a substance releases bubbles, it is converting some of its liquid into a gaseous state. The chemical properties do not change, only its present state. A most common physical change is that of watching ice melt in glass of water.
What is substance that undergo both chemical and physical changes?
Water is a common substance that undergoes both chemical and physical changes. Physical changes can include changes in state, such as melting or freezing, while chemical changes involve the formation of new substances through a chemical reaction, such as rusting or burning.
Changing form without a change in chemical properties?
This would be defined as a physical change. In chemistry, this would be defined as anything from a change in mass or volume to a change in state (solid, liquid, gas). As long as the substance does not change in molecular structure, it is mostly a physical change. Common indicators of a chemical change is change in color, production of light, production of extensive heat, production of uncommon smells, or even bubbling.
What are some common example of physical and chemical change that occur in the environment?
Some Physical Changes:> Water Cycle> Tearing of paper> Breaking of glassesSome Chemical Changes:> Photosynthesis ( the process of manufacturing food in plants )> ripening of fruits> burning> cooking
Is liquefying of air a physical change or chemical change?
Please note that a "change of state" involves TWO states, not just one. Using just the three most common states of matter: * A solid can change to a gas * A liquid can change to a gas * A gas can change to a liquid * A gas can change to a solid * A solid can change to a liquid * A liquid can change to a solid The first four changes in the list above involve gases.
What is the liquid used for dissolving?
Dissolving what?Water is a pretty common solvent.
