  • Density of gases

    Introduction Density can be described as a substance’s mass per unit volume at a particular temperature and pressure. A gas’s density is also determined by its mass divided by its volume. Additionally, once you are aware of a gas’s density, you may determine its molar mass. All gases density varies with temperature and pressure. In this article we…

  • Torricellis Law

    Torricelli’s law denotes that the flow speed of the fluid is equivalent to the speed of the object that is freely falling from a specific distance that is also equivalent to the height of the free surface of the fluid. Evangelista Torricelli was an Italian scientist who discovered the law in 1643. Later this law…

  • Surface Energy

    Introduction Surface energy is potential energy, applicable for liquid molecules where the molecules stand on the same surface as the liquid substances. The surface energy characteristically decreases when the molecules try to settle down to the bottom layer of the liquid surface. In the case of surface energy, equivalent attractive forces are commonly present between…

  • Properties of Gases

    Introduction Gas is a peculiar condition of matter wherein the molecules seem to be widely separated and continually moving at tremendous speeds. Gases possess no fixed size, shape, or volume. Ideal gases include those in wherein the intermolecular attractive forces become zero. In ideal gases, molecules travel at high rates of speed, which causes all particles to be far distant…

  • Pascals Law and Its Application

    Introduction The principle of fluid pressure is transmitted in the machines defined in “Pascal’s law” and it discovers the force direction. The direction of the force in the fluid container gets directed to the pressure point and the change of fore get occurs everyplace. The principle of Pascal’s is associated with fluid mechanics. The application…

  • Lava Lamp

    Introduction Every matter in the universe is composed of tiny particles called molecules. They attract each other with some attractive force. There exists an intermolecular force of attraction between molecules. Based on the force of attraction between the molecules, matter is classified into five categories. They are solid, liquid, gas, plasma, and Bose-Einstein. Solids are…

  • Bernoulli’s Principle

    Introduction Bernoulli’s principle can be underst ood it with a simple explanation that when fluid goes from a high-diameter pipe to a low-diameter duct, the speed of the fluid increases many times. Yes, it is true, but is it that simple? Not at all. This principle is quite complex, with many formulas and factors controlling it.…

  • Surface Tension

    Introduction Surface tension can be defined as the tendency of liquid surfaces to shrink into possible minimum surfaces in real time. In general, the small liquids in this process can shrink into the smallest feasible surface area. Here, the liquid can be in different states on the molecular level starting from the surface area to…

  • Reynolds Number

    Introduction Each particle of fluid follows a single path while flowing under a particular and steady condition of the flow. Fluid velocity, low in value has no such turbulent velocity. No lateral mixing happens during that fluid motion. The particle’s motion is followed by an order in which the moving particles flow in a parallel…

  • Relation Between Viscosity and Density

    Introduction Viscosity is used for the measurement of the thinness and thickness of the fluid. On the other hand, density measures the space between two particles of a fluid. Generally, with the increase in temperature, the particles of the fluid fall apart. Thereby, resulting in a decrease in fluid density. Decreases in fluid density affect…
