What physical properties would help you distinguish between a pure substance and a mixture?
If you wish to separate the constituents of a mixture, knowledge of the properties the constituent substances will help you figure out how to go about separating them. If you have any property (solubility in water, for example) that applies to at least one of you substances, and doesn't to another, you can use the property to separate them.
If you wish to separate a solution, knowing the solubility curves of each solute will allow you to separate by changing the temperature. For example, Potassium nitrate has a much higher solubility in water than sodium chloride at high temperatures, but at or near zero degrees Celsius, it has much less. So, if you had a solution of sodium chloride and potassium nitrate, you could lower the temperature drastically and most of the potassium nitrate will precipitate. This is but one example.
If you have a solid mixture, and a certain number of the substances in it will dissolve in water (or any other solvent), washing the mixture with the solvent will dissolve those, leaving everything else behind (you could filter the solvent out to separate the substances which don't dissolve)
If your substances are physically different in size, you could pass the mixture through a sieve (for example, to separate sand and gravel).
If one of your substances is magnetic, but others aren't, you could use a magnet to separate them.
What else can I help you with?
Every substance has its own melting point and what?
Every substance has its own unique melting point and boiling point. The melting point is the temperature at which a solid substance changes into a liquid, while the boiling point is the temperature at which a liquid changes into a gas. These physical properties are characteristic of each substance and can be used to identify and distinguish between different materials.
What is the relationship between molar density and the physical properties of a substance?
The molar density of a substance is a measure of how tightly packed its molecules are. It is related to the substance's physical properties such as its melting point, boiling point, and density. Generally, substances with higher molar density tend to have higher melting and boiling points, and are denser.
What is the difference between chemical and physical property?
A chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected for its chemical properties to be investigated.A physical property is any measurable property the value of which describes a physical system's state at any given moment in time. For that reason the changes in the physical properties of a system can be used to describe its transformations (or evolutions between its momentary states).
What is the difference between a physical and non-physical property?
Physical properties are characteristics that can be observed or measured without changing the substance's identity (e.g., color, mass). Non-physical properties, on the other hand, are abstract and cannot be directly measured or observed (e.g., beauty, morality).
What are some examples of physical properties scientist use to tell the differences between substances?
Scientists may use physical properties such as density, melting point, boiling point, and solubility to differentiate between substances. These properties are unique to each substance and can be measured to help identify the composition of a material.
What are two physical properties that could not be used to distinguish between water and ethanol?
Color and volatility
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
What are the characteristic properties of matter?
Characteristics properties of matter are things such as:densitycolorsizeshapetemperatureThese are just few of hundreds of characteristics
What is the name of the gap between the molecules in a substance?
The gap between molecules in a substance is known as intermolecular space. This space varies depending on the substance and affects the physical properties of the material.
Is not a physical property of water?
Perhaps the properties of space and time? Possibly the properties of a vacuum? You may be referring to "metaphysics" to distinguish between the real and the apparent properties of matter.
What is the difference between physical properties and chemical properties?
Physical properties of matter are those that can be seen or measured without changing the substance into something else. Chemical properties tell how the substance forms new substances when it reacts with something else.
Substance whose physical properties allow thermal equilibrium between two substances?
nothing it means no
Every substance has its own melting point and what?
Every substance has its own unique melting point and boiling point. The melting point is the temperature at which a solid substance changes into a liquid, while the boiling point is the temperature at which a liquid changes into a gas. These physical properties are characteristic of each substance and can be used to identify and distinguish between different materials.
What is the difference between a chemical and physical property?
physical properties are those that can be seen or measured without changing a material. chemical properties tell how the substance forms new substances when it mixes with something else.
What is the difference between chemical and physical properties?
Chemical properties describe how a substance interacts with other substances to form new substances, such as reactivity or flammability. Physical properties describe the characteristics of a substance that can be observed or measured without changing its chemical composition, such as color, density, or melting point.
What are the difference between a substance's physical properties and its chemical properties?
Chemical properties involve reacting with another substance. IE: burning of magnesium requires oxygen after which it is no longer magnesium. Physical properties do not. IE: metals are malleable, some very malleable, like copper wire can be bent with your hand. BUT it is still copper wire.
