The energy required to increase the surface area of a liquid due to intermolecular forces is known as surface tension. The surface tension does not change as the amount of matter changes and thus, it is
an intensive property
. Thus, surface tension is not an extensive property.
Is surface tension of water intensive or extensive property?
Option B. Density, C. Surface tension and D. Specific heat are
intensive properties
, because these are independent of the quantity of the matter present in the system and depend only on the nature of the substance.
Which of the following is an intensive property?
Temperature and pressure
belongs to intensive properties. It is a bulk property that does not depend on the size of the matter or that of the system.
Which property surface tension is?
Surface Tension: “The
property of the surface of a liquid that allows it to resist an external force
, due to the cohesive nature of its molecules.” … The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
Is surface area an intensive property?
Is surface area extensive or intensive?
Temperature remains intensive through- out the system
. This occurs even though surface properties, like surface area and luminosity, are not extensive, while bulk properties, like mass and volume, are extensive.
Is pressure an intensive property?
Intensive properties are properties that do not depend on the quantity of matter. For example, pressure and temperature
are intensive properties
. Energy, volume and enthalpy are all extensive properties. Their value depends on the mass of the system.
Is density intensive or extensive property?
Density is an
intensive property of matter
that illustrates how much mass a substance has in a given amount of volume.
What is the difference between intensive property and extensive property?
Summary. An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and
not
on the amount.
Is entropy an extensive property?
The internal energy is an extensive quantity. The temperature T is an intensive property, independent of the size of the system. It follows that the entropy S
is an extensive property
.
Is Weight intensive or extensive?
Extensive properties
vary with the amount of the substance and include mass, weight, and volume. Intensive properties, in contrast, do not depend on the amount of the substance; they include color, melting point, boiling point, electrical conductivity, and physical state at a given temperature.
Why is surface tension intensive property?
The surface tension does not change as the amount of matter changes
and thus, it is an intensive property. Thus, surface tension is not an extensive property. … The density does not change as the amount of matter changes and thus, it is an intensive property.
Is pH an intensive property?
As the pH is the measure of concentration of H
+
ions and as concentration is an
intensive property
so pH is also an intensive property.
Which property is an intensive property of the system?
Intensive and extensive properties
By contrast, an extensive property of a system does depend on the system size or the amount of material in the system. According to the definitions,
density, pressure and temperature
are intensive porperties and volume, internal energy are extensive properties.
How do you explain surface tension?
Surface tension is
the tendency of liquid surfaces at rest to shrink into the minimum surface area possible
. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.
What is surface tension with example?
surface tension, property of a
liquid surface displayed
by its acting as if it were a stretched elastic membrane. This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles. Because of this property, certain insects can stand on the surface of water.
What liquids have surface tension?
There is only one liquid having higher surface tension and that’s
mercury
which is a liquid metal with a surface tension of almost 500 mN/m.
