Proven by a assosiative scientific teacher:
Signs of physical changes can be quite numerous,
but the main numbered would be the following---
chemical:
color change
fizzing structure
bubbled buildings
chemical rearranged(nonsense as in disappear)
cannot be reserved
and a frequent suiren tempetarure change

hot steam or bubbles will occur
liquid may change colors but still smell the same
the two substances may be mixed but neither one will dissolve
hope this helps!

Is milk sours a example of physical change?
No, a chemical change. Taste and smell are indicators of chemical composition, so a change in those would indicate a chemical change.
Is this statement true Ice being broken into small bits is an example of a chemically change?
No it is not, as the ice will still retain its chemical properties. This is an example of a physical change. Remember that the indicators of a chemical change are a change in colour, a change in odour, a change in temperature, the formation of a precipitate, or a gas being given off.
How indicators works?
pH indicators change their color according to the pH of a solution.
What are the indicators of grinding a pepper?
Intrnal indicator
Are sensations of feeling hot or cold reliable indicators of climate change?
No. Nor are they necessarily indicators of ambient temperature change.
When something is blue is that a physical or chemical change?
indicators of a chemical reacton include color change, heat given off, and gas produced. indicators of a physical change are phase changes, changes in shape, and changes in size. "Being blue" is not a change at all. It's a condition.
What is an emample of a chemical change?
The following are indicators of chemical changes: ... For example, changing the color of a metal does not change its physical properties.
Is milk sours a example of physical change?
No, a chemical change. Taste and smell are indicators of chemical composition, so a change in those would indicate a chemical change.
Is mixing oil and water chemical or physical?
It is a physical change because the oil and the water do not change in chemical composition.

Why do indicators in chemistry change color when placed in different substances?
The indicators which change color is litmus paper strips.
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.
How indicators works?
pH indicators change their color according to the pH of a solution.

Are sensations of feeling hot or cold reliable indicators of climate change?
No. Nor are they necessarily indicators of ambient temperature change.
What are indicators of a chemical change when 2 substances are mixed together?
Some indicators include:Change in TemperatureChange in ColorNoticeable Odor (after reaction has begun)Formation of a PrecipitateFormation of BubblesWhen two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical reaction is probably occurring. These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical. This is because the composition of the car has not changed. Proceed with caution.
Can indicators change colour twice?
Yes.
