It indicates a chemical reaction because it changes from one substance to another.
Not always but they can. They may simply be an indication of a phase change, as when water boils. This is usually counted as a physical change rather than a chemical change. But if you add baking soda to vinegar, you will see bubbles as a result of a chemical change.

The most common indicators of a chemical reaction are: 1. A color change. 2. A temperature change. 3. Bubbles (indicating a gas) 4. A precipitate (a solid that settles out of liquids) A chemical change can feature all, none, or any combination of these.
In and of itself, no. Both chemical and physical changes can create bubbles.
It is a physical 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.

When you mix liquids with gas, the gas can dissolve in the liquid or form bubbles within the liquid. This can alter the properties of the liquid, such as its density and ability to flow. The gas molecules can also escape from the liquid if the conditions change.
The answear is when salt and water react together
Change in color: If the substance changes color during a reaction, it may indicate a chemical change. Formation of gas: Production of gas bubbles, fizzing, or bubbling is a sign of a chemical change. Temperature change: Significant heat or cooling effects can indicate a chemical reaction is occurring. Formation of a precipitate: When a solid substance forms in a solution, it suggests a chemical change has taken place.
Contour lines that are close together indicate steep terrain or a rapid change in elevation. The closer the contour lines are, the steeper the slope.
Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.

On a topographic map, contour lines that are closer together indicate a steeper slope.
A chemical reaction can result in any or all of the following: - a change in temperature (up or down) - a change in color - a smell that wasn't there before - the formation of bubbles (indicating the production of a gas) - the formation of a precipitate
Change in temperature: If the temperature of the reactants increases or decreases significantly. Formation of a precipitate: A solid substance formed when two liquids react. Change in color: Observing a change in color before and after the reaction. Evolution of gas: Gas bubbles forming or a gas being released during the reaction.
