What else can I help you with?
Do bubbles indicate a physical or chemical change?
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.
Why can liquid change but solids cannot?
The forces holding the atoms together are weaker in liquids than in solids -Apex
What identifies that a chemical reaction has occurred?
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.
Is bubbles a chemical change?
In and of itself, no. Both chemical and physical changes can create bubbles.
Is it a physical or chemical change champagne bubbles when the cork is removed?
It is 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.
Do bubbles indicate a physical or chemical change?
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.
What happens when you mix liquids with gas?
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.
What can A change in a physical property of matter can indicate?
The answear is when salt and water react together
What are four things that indicate that a chemical change may have taken place?
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.
What On the topographic map contour lines that are close together indicate a?
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.
Do bubbles appear when a chemical change is happening?
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.
Why can liquid change but solids cannot?

On a topographic map contour lines that are closer together indicate?
On a topographic map, contour lines that are closer together indicate a steeper slope.
What are the four occurrences indicate a chemical reaction has occurred?
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
What are four types of evidence that indicate that a chemical reaction may have taken place?
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.
What identifies that a chemical reaction has occurred?
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.
