The Escape Velocity of Earth
Introduction It is often that we wonder how it is possible for any mass to deny the gravitational pull of the earth. The mass of the earth is 5.972×1024kg5.972×1024kg is quite heavy and based on its mass, its pull will be much stronger in nature. This leads to the question of its possibilities and that provides the…

Solar System
Introduction The solar system includes several non-steller objects that comprise gases as well as lesser bodies. The sun locates in the center of this system and all the planets are turning around the Sun. The planets are also surrounded by their satellites. Besides this, countless asteroid comets along with different icy bodies are included in…

Difference Between Stars and Planets
Introduction Planets and stars, being astronomical bodies are held together because of their individual gravity. Distinguishing stars from planets is very important to identify them as different astronomical bodies. Most of the stars possess a particular shape and from the Earth, these are deemed to be a size of a mere dot. The speed of…

Difference Between Asteroid and Meteoroid
Introduction Astrophysics is the major subject to develop knowledge about celestial objects. The study of the sun, the comets, the stars, asteroids, meteoroids, and galaxies is called astrophysics. The birth of the stars and their life and the end of the stars are studied through this. Asteroids are small celestial objects which orbit around the…

Constellations
Introduction Once Shyam and Sita visited their village and went on the roof in the moonless night. They are looking up in the sky and saying that there are several twinkling stars there and they are looking very beautiful. Suddenly Sita asked Shyam from which the stars are made up of and why they are…

Monatomic Gases
Monatomic gases are composed of single atoms, making them the simplest type of gas, with common examples including noble gases like helium, neon, argon, krypton, and xenon. These gases adhere closely to the principles of kinetic molecular theory, where their behavior is largely determined by the motion of individual atoms. They typically exhibit ideal gas…

Gas Constant
The gas constant, denoted by RRR, is a fundamental constant used in various equations of state for gases, including the ideal gas law, which is expressed as PV=nRTPV = nRTPV=nRT. Here, PPP represents pressure, VVV is volume, nnn is the number of moles of gas, TTT is the absolute temperature in Kelvin, and RRR relates…

Changing States Of Matter
Changing states of matter involves the transition of substances between solid, liquid, gas, and, in some cases, plasma, primarily influenced by temperature and pressure. Melting occurs when a solid absorbs heat, causing its molecules to gain energy and transition to a liquid, while freezing is the reverse process where a liquid loses heat and solidifies.…

Behaviour Of Gas Molecules
Gas molecules exhibit distinct behaviors governed by the principles of kinetic molecular theory, which states that they are in constant, random motion, colliding elastically with one another and the walls of their container. This motion produces pressure, as gas molecules exert force during collisions, with factors like temperature and volume influencing this dynamic. For example,…

Size of the Nucleus
Introduction In the field of physics, the identification of fundamental structures is quite essential for the study of nuclei. However, the structure of the nucleus would not have been known to the world if Ernest Rutherford would not conduct the experiment of gold foil in understanding the structure of atoms. This is noted that earlier,…
