which of the following is not a physical property?

Question

a. boinling point
b. flamability
c. solubility
d. color

Answer 1

briefly its b. flammability ..its a chemical property which defined as the ease with which a substance will ignite, causing fire or combustion.

for more information :

A physical property is any aspect of an object or substance that can be measured or perceived without changing its identity. Physical properties can be intensive or extensive. An intensive property does not depend on the size or amount of matter in the object, while an extensive property does. In addition to extensiveness, properties can also be either isotropic if their values do not depend on the direction of observation or anisotropic otherwise. Physical properties are referred to as observables.

Often, it is difficult to determine whether a given property is physical or not. Color, for example, can be "seen", however, what we perceive as color is really an interpretation of the reflective properties of a surface. In this sense, many ostensibly physical properties are termed as supervenient. A supervenient property is one which is actual (for depend on the reflective properties of a surface - it is not simply imagined), but is secondary to some underlying reality.

This is similar to the way in which objects are supervenient on atomic structure. A "cup" might have the physical properties of mass, shape, color, temperature etc, but these properties are supervenient on the underlying atomic structure, which may in turn be supervenient on an underlying quantum structure.

In the common sense, physical properties can be separated from nonphysical properties. Typically a nonphysical property is associated with a living being. Anger and love are not things which are part of the mechanics of the universe, but terms we use to discuss mental states.

Literally, the physical properties of an object are defined traditional in a Newtonian sense, the physical properties of an object are angle, angle velocity, area, capacitance, density, electric charge, electric current, electric field, electric potential, energy, force, frequency, length, location, magnetic field, magnetic flux, mass, power, pressure, resistance, temperature, velocity and volume.

Answer 2

Flammability is a chemical property, not a physical one. It is the ability of a substance to react with oxygen (ie. a chemical reaction).

Boiling is clearly Physical property, color is also a physical property that is affected as one person said by the grain size and composition but is a physical property.
Solubility is the most tricky one, but since it is a reversible process that do not involve a chemical change, it is also a physical property. Think about salt and water, salt dissolves in water, but if you evaporate the water it precipitate back again.

Answer 3

Let's see. Most substances have a boiling point, which implies a change in energy being applied to it (either cooling or heating, depending on the beginning state of the substance), and which depends in part on the vapor pressure above the boiling liquid). Flammability--well, substances are either flammable or not in a given circumstance, so it might be thought of as a physical property dependent on other conditions. Solubility--again, like flammability, all substances can be made to dissolve in some reagent. And, given a concentration of that reagent and it's temperature, the amount of a substance that can dissolve is determinable, so solubility is indeed, a physical property (or, like one answer stated, a physico-chemical property).

Like the other properties the color of a material is dependent on other conditions (the spectral characteristics of ambient light, in the case of color); (note the change in colors of some materials in mercury vapor light as opposed to incandescent light). I guess one could conclude that all the properties listed are physical properties, and all are dependent on ambient conditions. But......

The one, in my opinion, that comes closest to not being a physical property is color. I say that because color can also depend on particle size. Take most metals, for example. Metals often are silvery in large pieces, but many metals when powdered are black. Some minerals have powders of a different color than the main mass (specular hematite (iron oxide), though silvery in hand specimens, yields a brick red powder, and zinc sulfide (sphalerite), though usually brown or black in hand specimen, yields a white powder (pure specimens are white, however). When a property changes simply due to the size of the specimen being considered, I don't think of it as a physical property. The boiling point, flammability, and solubility do not change with particle size (though the SPEED at which reactions take place may change). They are, then, the true physical properties.

Answer 4

Color

Answer 5

It is a liquid is a physical property. It reacts with many substances is a chemical property.

Answer 6

All are physical properties although solubility can be argued as being a chemical property as well.
The other three are definitely physical properties.

Answer 7

Color, since physical properties can exsist whether there is light present or not. Color can't.

Answer 8

boiling point
