Specific Heat Capacity

Specific Heat Capacity Specific heat capacity is the amount of energy required for raising the temperature of the substance per unit of the mass. The specific heat capacity of the materials is a physical property. It is also a good example of the extensive properties as its value is proportional to the size of the … Read more

Change of State

The matter is always in the changing states and the changes in the state of the matter are the physical changes. These changes are reversible and there is no involvement of the chemical properties or the chemical makeup. The common changes of the state include the freezing, melting, deposition, sublimation, condensation, and vaporization. Temperature, Energy, … Read more

Thermal Expansion of Gasses

The main concept behind the thermal expansion of the gasses is the heating and cooling processes. As compared to the other materials, the behavior of the gasses is much complicated, as they will expand, as much as the pressure will allow the expansion. Generally, the expansion of the gasses is much more than solids and … Read more

Thermal Expansion of Liquids

The liquids do not have any specific shape and they take the shape of the container in which they are placed. Thus, the liquids can be specified due to their volume. On heating of the liquid in the container, the heat is flowing to the liquid through the container which means that first there is … Read more

Latent Heat Capacity

Latent heat is the energy released or absorbed by the material or substance during the changes in its physical state, that occurs without causing any changes in its temperature. The latent heat which is associated with the freezing of liquid or melting of the solid is known as the heat of fusion. Whereas, the latent … Read more

RMS Speed of Gas Molecules

Root-Mean-Square Speed The root-mean-square speed is essential in measuring the average speed of particles contained in a gas, defined as vrms=√3RT/M. In Kinetic Molecular Theory, gasified particles are in a condition of constant random motion; each particle moves at a completely different pace, perpetually clashing and changing directions consistently velocity is used to describe the … Read more

Degrees of Freedom

In three-dimensional area, 3 degrees of freedom are related to the movement of a particle. A diatomic gas molecule has half-dozen degrees of freedom. This set may be decomposed in terms of translations, rotations, and vibrations of the molecule; the center of mass motion of the entire molecule accounts for 3 degrees of freedom. Additionally, … Read more

Anomalous Expansion of Water

Water has a commonplace in our daily lives and it is regarded as the typical liquid. Water is one of the most unusual liquids that can be ever encountered. It is often said that life on the earth is dependent on the water, due to its properties. In terms of gasses, the water is one … Read more

Thermal Expansion of Solids

In physics, the thermal expansion can be defined as any change in the width, length, volume, and height of any material by changes in the temperatures. In the solids, the thermal expansion is very evident as the atoms of the solids are densely packed. Description of Thermal Expansion in Solids Various solids are made up … Read more

Kinetic Theory of Gases – Concept of Pressure

Origin of Pressure Pressure is explained by kinetic theory of gases as arising from the force exerted by molecules or atoms impacting on the walls of a container. In Newtonian mechanics, if pressure is the force divided by the area on which the force is exerted, then what is the origin of pressure in a … Read more
