Viscosity changes when another agent is added to a fluid. For example, paint has a fairly thick viscosity and if intending to apply it using a spray gun, one would need to add thinners, varsol, or turpentine to the paint to thin it out so that it will pass through the gun. Thus changing the viscosity.
No, viscosity is a physical property of a substance that describes its resistance to flow. It is not a chemical change because it does not involve any change in the chemical composition or properties of the substance.
Viscosity is nor a change, it is a property.
A physical property.
It changes by rising temperatures and lowering temperatures.
Higher temperature= Less viscosity (resistance)
Lower temperature= More viscosity (resistance)

Is viscosity a chemical or a physical change?
viscosity is a physical characteristic not a physical change. it is the thickness of a substancephysical changes would be if it turned from solid into a liquid.for example a chocolate bar goes through a physical change when it becomes melted chocolate.
How can you be certain that a chemical change has occurred?
Some signs that indicate a chemical change has occurred include the formation of a gas, a precipitate, a color change, or the release of heat or light. Chemical changes involve the breaking and forming of chemical bonds, resulting in the creation of new substances with different properties than the original reactants.
What would indicate that a chemical change may be occurring?
Some indications that a chemical change may be occurring include the formation of a precipitate, a change in color, the evolution of gas, or a change in temperature. These can all suggest that a new substance is being formed with different chemical properties than the starting materials.
How will you know that a chemical reaction has occurred?
You can identify a chemical reaction by observing changes such as the formation of a gas, a precipitate, heat, light, or a color change. Moreover, you may notice changes in properties such as odor, temperature, or pH levels. Testing for the presence of new substances or products can also confirm a chemical reaction has taken place.
When two substances are mixed they might form a new substance What would indicate that a new substance has been formed?
A new substance is formed when there is a chemical reaction resulting in a change in chemical composition. Indications include a change in color, formation of a precipitate, evolution of gas, or change in temperature.

What can you talk about as a chemical reaction?
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence
Which item is a sign of chemical change?
Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds.
How would you determine if a chemical change had occurred?
Some characteristics of a chemical change are: - change of smell - change of color - release of gases - change of temperature - formation of a precipitate - change of the aspect - change of pH in solutions - change of viscosity - flames or explosion etc.
What always occurs during a chemical change?
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence
What can a chemical change be defined as?
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence - formation of new compounds
How do you determine a chemical change?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion - possible chemiluminescence - formation of new compounds
How can a chemical reaction be observed?
Some indications may be: - release of a gas - formation of a precipitate - change of color - change of odor - change of pH - change of viscosity - change of the aspect - etc.
Why does this indicate that a chemical reaction might have occurred?
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence
What is a sign that a chemical change has definitely occurred during his experiment?
Some signs for a chemical reaction are: change of the color, release of a gas, change of the temperature, formation of a precipitate, pH modification, viscosity variation, a change of the odor or taste, etc.
What is a sign that chemical change has occurred?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion- possible chemiluminescence -formation of new compounds
How could you change the viscosity of the substances?
You can change the viscosity of a substance by adjusting its temperature- generally, increasing temperature decreases viscosity and vice versa. You can also alter the composition of the substance by adding viscosity modifiers or solvents to increase or decrease viscosity accordingly. Mixing different substances together can also affect the overall viscosity of the mixture.
