Have we thought why honey moves so much slowly in comparison of water? Alternatively, why does oil spread differently than juice? This is not all magic but is a quality of fluids and this solution can be found in a fluid’s viscosity. Honey What is Viscosity? A fluid’s viscosity is a measurement of its resistance … Read more
Ion mobility in a solution is essential for conducting electricity. The ability of an electrolytic solution to permit electric current to flow through it is known as its conductance. This characteristic is essential to electrochemistry and has many uses in both daily life and industry. Electric current What Conductance of Electrolytic Solutions? Dissolving in water, … Read more
Bernoulli’s principle describes how a fluid behaves while it moves. It creates a connection between a fluid flow’s height, velocity, and pressure. The Swiss mathematician and physicist Daniel Bernoulli developed the principle in 1738, and it bears his name. It is extensively utilised in a number of disciplines, such as engineering, aviation, and medicine. Bernoulli’s … Read more
Formula in electrochemistry is the Nernst Equation support in figuring out an electrochemical cell’s electrode potential in unusual circumstances. It shows that how temperature, the concentration of the reactive species, and the cell potential and standard cell potential relate to one another. Preamble of Nernst Equation The electrode potential in an electrochemical cell is the … Read more
Fluid dynamics is vital, especially when we study about fluid motion. Streamline flow, sometimes called as laminar flow, is one of the most basic forms of fluid flow. It has a big impact on environmental science, engineering, and medicine it helps us to understand how gases and liquids travel under different circumstances. Medicine What is … Read more
Electrochemical cells transform chemical energy into electrical energy through redox processes. These cells are essential for many uses, such as industrial operations, batteries, and electrolysis. Batteries Definition and Working Principle The anode (anode is generally positive side of cell) and cathode (cathode is generally negative side of cell) of an electrochemical cell are both submerged … Read more
