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

What Kind Melted Crayon What Is It Physical Or Chemical Change Of Indicators Of Change?
Melting crayons is a physical change. When crayons are heated, they change from solid to liquid without altering their chemical composition. Indicators of this physical change include a change in state and temperature, as well as the ability to solidify again upon cooling. However, the crayons retain their original color and chemical properties throughout the process.
How are pH indicators classified?
pH indicators are classified based on the pH range over which they change color. They can be classified as either acidic, basic, or universal indicators. Acidic indicators change color in acidic solutions, basic indicators change color in basic solutions, and universal indicators change color over a wide pH range.
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 the indicators of grinding a pepper?
Intrnal indicator
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 acid-base indicators?
These indicators change the color depending on the pH of the solution.
Are sensations of feeling hot or cold reliable indicators of climate change?
No. Nor are they necessarily indicators of ambient temperature change.

Intrnal indicator
Is an indicator's reaction in acids and bases a chemical change?
No, an indicator's reaction in acids and bases is a physical change. Indicators change color based on the pH of the solution they are in, but the chemical composition of the indicator remains the same.
Do acids effect indicators?
Yes, acids can affect indicators by changing their color. Indicators are substances that change color in response to the acidic or basic nature of a solution. Acids can cause indicators to change color depending on their pH level.
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 many types of indictors are used in titration?
There are two main types of indicators used in titration: color indicators and pH indicators. Color indicators change color at specific pH ranges to indicate the endpoint of the titration, while pH indicators change color based on the pH of the solution.
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.
