We can understand sliding friction as the resistance force created between any two bodies when sliding against each other. This friction is also called kinetic friction and it is defined as the force that is required to keep a surface sliding along another surface. It hangs on two variables-…
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. Yeast is a very useful microorganism and is used to cause fermentation. Yeast grows by fermentation, feeding upon sugars. During fermentation, yeast converts glucose into ethanol and carbon dioxide and is therefore used in beer and wine…
Nitrogen gas is used for packing the packets of chips because it is an inert gas, and it prevents the oxidation of oils present in the chips. This keeps the chips fresh and has no or less breakage. Nitrogen is often filled in chips packets to prevent rancidity as it…
Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms, and electrons, transfer disorganized microscopic kinetic and potential energy when joined, known as internal energy. Conduction takes place in most phases: solid,…
Heat transfer is the transfer of heat or thermal energy between physical systems. So when there is a temperature difference between two bodies, heat is transferred from the hot body to the colder body. There are three common modes of heat transfer – conduction, convection, and radiation. In this article,…
Radiation The color of your home’s exterior influences a lot more than the look of your house. The outside of your house either absorbs or reflects heat, making the inside hotter or cooler. That means the color you select for the outside of your home affects the temperature inside,…
Osmosis is a vital process in biological systems, as biological membranes are semipermeable. In general, these membranes are impermeable to large and polar molecules, such as ions, proteins, and polysaccharides, while being permeable to non-polar or hydrophobic molecules like lipids as well as to small molecules like oxygen, carbon…
A well-known chemistry experiment is done by placing an egg (raw or boiled) into a container filled with Vinegar. After a few days, something exciting is observed: the egg becomes rubbery and bouncy. The eggshell is formed by calcium carbonate (CaCO3), a salt in limestone, plaster, marble, chalk,…
The vacuum flask consists of two vessels, one placed within the other and joined at the neck. The gap between the two vessels is partially evacuated of air, creating a partial-vacuum which reduces heat conduction or convection. Heat transfer by thermal radiation may be minimized by silvering flask surfaces…
It could simply be that black paint is cheaper… But I believe that the external coils on the back of refrigerators are painted black for the following reason: There is a rule in nature that says “a color that is better at absorbing heat is also better at radiating heat.” …
We encounter various types of lever in our everyday lives: opening a drink with a bottle opener, cutting paper with scissors, taking the lid off a paint pot using a screwdriver, and – the simplest of all – playing on a seesaw in the park. Yet, the principle of…
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided…
According to heat definition, it is one of the essential forms of energy for the survival of life on earth. Transfer of heat takes place from one body to another due to difference in temperature as per thermodynamics. We use heat energy for various activities like cooking, ironing, transportation,…
Microorganisms A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. 0
A microorganism is a living thing that is too small to be seen with the naked eye. Examples of microorganisms include bacteria, archaea, algae, protozoa, and microscopic animals such as the dust mite. Microorganisms are found virtually everywhere, except for environments that have been made artificially sterile by humans. Even…
Geometry is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space that are related with distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a geometer. 0
In mathematics, the Fibonacci numbers, commonly denoted Fn, form a sequence, the Fibonacci sequence, in which each number is the sum of the two preceding ones. The sequence commonly starts from 0 and 1, although some authors omit the initial terms and start the sequence from 1 and 1 or…

Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The xylem, vessels and tracheids of the roots, stems and leaves are interconnected…
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. Mass flow of liquid water…
Soap molecules consist of a hydrophilic (“water-loving”) end and a hydrophobic (“water-fearing”) end. Water molecules are polar molecules that can dissolve other polar molecules. Fat (and oil) molecules are nonpolar molecules, so they cannot dissolve in water. Milk is a mixture of water, fat, vitamins and minerals. When soap is…
Let’s make our own Glider Plane! A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines…
Air is a mixture of many gases. The molecules of gases present in air have weak inter-molecular forces of attraction. Due to this reason these molecules lie far apart from each other i.e. there are large vacant spaces present between these molecules. So, these molecules are free to move in any direction.…
