Physical changes can be indicated by changes in appearance, texture, size, or state of matter without altering the chemical composition. Chemical changes, on the other hand, can be indicated by the formation of new substances, changes in color, temperature, odor, or the production of gas.
physical=A physical change does not produce a new substance.
chemical= A chemical change produces a new substance.

Do the bubbles in a pot of boiling water for noodles indicate chemical change?
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.

What does not signal a chemical change color change or production of light and heat or production of gas or change in state?
A change in state does not necessarily indicate a chemical change. Melting, freezing, boiling, or condensing of a substance are physical changes that do not involve a change in the chemical composition of the substance.
What change in a physical property of matter indicate?
a physical change or a chemical change
What change in a physical property of matter can indicate?
A change in a physical property of matter can indicate a physical change, such as a change in state (solid to liquid), color, shape, or texture. These changes do not alter the chemical composition of the substance.
Why does the sound of thunder indicate a physical change rather than a chemical change?

Which Property that could be used to indicate physical or chemical change?
state
Is heat light and change in odor indicate a physical change?
Heat, light, and change in odor can indicate a physical change depending on the context. For example, melting ice into water is a physical change because it does not alter the chemical composition of the substance. However, if a substance undergoes a chemical reaction that results in heat, light, and change in odor, then it would be considered a chemical change.
What can indicate physical or chemical changes depending on the cause of the change?
People can
Which observation does not indicate that a chemical reaction has occured?
A change in state, such as boiling or melting, does not always indicate a chemical reaction has occurred. It could be a physical change.
Do the bubbles in a pot of boiling water for noodles indicate chemical change?
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
Does gas always indicate a chemical change?
No, the presence of gas does not always indicate a chemical change. Gas can form due to physical processes such as evaporation or changes in temperature, without any chemical reactions taking place.

Is milk sours a example of physical change?
No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.
