Why Jupiter is a Failed Star?

 

Why Jupiter is a Failed Star?

Jupiter, a gas giant, lacks the mass to initiate sustained nuclear fusion, a defining characteristic of stars. Primarily composed of hydrogen (90%) and helium(10%), similar to stars, Jupiter's insufficient mass prevents it from achieving the necessary temperature and pressure for fusion, relegating it to a planet rather than a star.

Science experiment DIY: Flame without Matchstick

Science experiment DIY: Flame without Matchstick 



When glycerine comes into contact with potassium permanganate, it initiates a rapid oxidation reaction. 

The reaction produces heat, light, and flames due to the rapid release of energy as the molecules rearrange and form new compounds. 

The manganese dioxide formed as a product of the reaction also contributes to the exothermic nature of the reaction. 

The reaction is highly exothermic, meaning it releases a significant amount of heat, enough to ignite any combustible materials nearby. 

 Due to the intensity of the reaction and the potential hazards involved, this method should only be performed by individuals with proper training and in a controlled environment. It's important to exercise caution and adhere to safety guidelines when experimenting with chemical reactions.

Science & History behind Voter's Ink

Science & History behind Voter's Ink

 For the upcoming election, an order of 26.5 lakh phials, each with a capacity of 10 ml, has been placed.

The ink to be used contains 20 percent silver nitrate, a colorless compound that becomes visible under ultraviolet light, including sunlight, remaining detectable for up to 72 hours post-application.

This ink is remarkably resistant to various substances such as soap, liquids, home-cleansing agents, and detergents.

Initially developed by CSIR, India, it was later patented by the National Research Development Corporation (NRDC) in New Delhi.

Mysore Paints & Varnish Ltd., a Karnataka Government Undertaking licensed to manufacture the ink since 1962, continues its role in providing this specialized electoral ink.

Skin loses cells every minute

Skin loses cells every minute

The human body constantly undergoes renewal, shedding old cells to make way for new ones. Skin, the body's largest organ, exemplifies this with remarkable efficiency. 

Every minute, approximately 30,000 skin cells are sloughed off, replaced by fresh ones from the lower layers. 

This shedding process, known as desquamation, helps maintain skin health, removing dead cells and debris while promoting regeneration

Nature's Mystery: The Triple Point of Water Explained

Nature's Mystery: The Triple Point of Water Explained

The triple point of water is a unique physical state where water exists simultaneously as a solid, liquid, and gas. 

At precisely 0.01°C and 611.657 pascals of pressure, water's solid form (ice), liquid form, and gaseous form (water vapor) coexist in equilibrium. 

This point is significant in thermodynamics and metrology as it serves as a reference for defining the Kelvin temperature scale and the standard atmospheric pressure.

Understanding the triple point of water is crucial for calibrating thermometers and pressure gauges accurately. 

It showcases the fascinating interplay between temperature, pressure, and the states of matter.
