The restoring forces are mainly responsible for the oscillations of the system. So, the restoring forces are always involved in the movement of the masses which are attached to the simple pendulums and springs. When someone is jumping off a bridge over the river, that is attached to the special kind of the elastic cord … Read more
The mean free path λ of a gas molecule is the normal path length which is between collisions and is given by, λ = 12√πd2NV Let’s look at the motion of a gas molecule inside an ideal gas, a typical molecule inside an ideal gas will abruptly change its direction and speed as it collides … Read more
When we deal with the atoms, molecules and formula units which are extremely small, far, far smaller than grains of sugar. Counting atoms or molecules is not only unwise, it is absolutely impossible. One drop of water contains about 1022 molecules of water. If you counted 10 molecules very second for 50 years without stopping … Read more
Calorimetry is used for the determination of the heat flow in the chemical reactions, for measurement of the heat of solvation, and characterization of the phase transitions. Generally, the gasses have the two specific heats of the Cp and Cv, at the constant volume and the constant pressure, whereas the solids and liquids have the … Read more
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
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
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
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 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
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
