  • Mean Free Path : Definition and Formula Derivation

    when a molecule travels and collides with various molecules, then it travels a free path in the vessel. anyhow, all the free paths of the molecules are not equal. so, if we take the average of all these free paths,…

  • collision frequency (molecule is traveling in the center of the cylinder)

    Collision Frequency Definition & Formula

    What is Collision Frequency? if we follow a single molecule in one cm3 of the gas and want to observe that, how many collisions are being faced by this molecule in one second, then it will be collision frequency of…

  • collision diameter (diagram of two colliding molecules)

    What is Collision Diameter ? Definition & Examples

    In order to do a collision, the molecules approach each other. at the time of contact of the outer boundaries, there is a limit beyond which they cannot come close to each other. this is called the distance of the…

  • Law of Equipartition of Energy

    In physical chemistry, for a monoatomic gas, the translational energy associated with one mole of the molecule at any temperature is 3/2RT. According to the law of equipartition of energy, 1/2RT is expended along the x-axis, 1/2RT along the y-axis…

  • Heat Capacities of Gases: (at constant volume and Temperature)

    Matter exists due to the possession of energy and there is a close interaction between energy and matter. the matter has the capability to retain to a greater or lesser extent a certain amount of energies. in this article, we…

  • examples and applications of viscosity

    What are Examples and Applications of Viscosity in Everyday Life?

    What is viscosity? viscosity is defined as the property of resistance to flow in a liquid. All the fluids have different rates of viscosity some are highly viscous and others are low viscous, for example, water has low viscosity than…

  • Branches of chemistry

    Different Branches of Chemistry and Their Examples

    The Study of atomic matter is said to be chemistry. Typically it includes the chemical reaction of matter their properties, behavior, and structure with composition. There are numerous branches of chemistry. but majorly five branches of chemistry were found which…

  • what is viscosity

    Viscosity Definition and Formula with Units

    Viscosity is a common observation that thick liquids like honey and mobile oil, flow slowly than many organic liquids like benzene and toluene, etc. It means that different rates of flow of liquids depend upon a certain property and that…

  • properties of liquid

    Properties of Liquid Based on Certain Measurements

    Constitutive and Additive Properties of Liquids: Matter exists in three states i.e., gases, liquids, and solids. The chapter on the liquids is mostly concerned with the discussion of the important physical properties of liquid-like vapor pressure, viscosity, surface tension, refractive…

    Best Cement Industry in Pakistan with their Production & Capacity

    Cement Industry in Pakistan: At the time of partition in 1947, there were four plants producing 3, 30,000 tons of cement every year. However, in 1953 – 54 the production of cement rose to 6, 60,000 tons. In 1956 P.…
