Can physical propertys be observed then reversed back?
Some physical properties can be reversed back after they have been observed, while others cannot. Properties like temperature, magnetization, and electrical conductivity can often be reversed by changing the conditions that caused them. However, certain irreversible changes may occur due to chemical reactions or physical deformations.
Why do chemical properties change?
when something undergoes a chemical reaction, its properties may change. meaning the properties could be different than whhat they started off as.
Differences between chemical and physical properties?
In a physical change of matter, no new substances are formed. However, physical properties such as size, shape, color, or phase may change. Dissolving, melting, evaporating and grinding are examples of physical change.As a result of chemical change, one or more new substances with new and different properties are formed. The new substances are different from the original substance. Burning and the rusting of iron are examples of chemical change.
Why do chemical reactions change properties?
when something undergoes a chemical reaction, its properties may change. meaning the properties could be different than whhat they started off as.
A factor that may change as a result of the changes made to the independent variable. it is measurable or observed?
The dependent variable is the factor that may change as a result of changes made to the independent variable. It is the variable that is measured or observed in response to the manipulation of the independent variable in an experiment.
What is the variable that may or may not change when the independent variable is changed?
The variable that may or may not change when the independent variable is changed is the dependent variable. It is the variable that is being measured or observed in an experiment and is expected to change in response to the manipulation of the independent variable.
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.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
How do the properties of the new substances compared with the properties of the original substance after a chemical change takes place?
They may be similar or totally different.
What happens to the chemical and physical properties of a substance formed in a chemical reaction?
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
What is the difference between between chemical and physical properties?
Physical property is an aspect of matter that can be observed or measured without changing, Chemical property may only be observed by changing the chemicals identity of a substance. (this was copied off a scientific website) :)
Which properties of a rock may change as the rock become metamorphic?
crust deeper rock
