Introduction In this tutorial, information regarding the properties of waves such as phase velocity and group velocity will be discussed with proper exemplification, in physics, the wave can be defined as a mare disturbance identified on a plane surface. Based on this concept, the definitions of group and phase velocity will be discussed in this tutorial. Along with this, the tutorial will include the relation and the differences that have been shared between these two properties of a wave. What is group velocity? Figure 1: Group velocity The group velocity of waves can be explained as the velocity of ... Read More

Introduction Every matter in the universe is made up of small particles called molecules. According to the distance between the molecules and the attractive force, they are classified. Different matters have different properties. The properties of matter include mass temperature, density, volume pressure, etc. The transformation of heat is done in matters by conduction, convection, and radiation. Thermodynamics deals with the thermal energy which comes from heat. Thermodynamics comes under the branch of physics which explain the relation of heat, work, and temperature with energy, entropy. Now, we are going to discuss the thermodynamic system, process, adiabatic process and their ... Read More

Introduction The division of magnetic induction in the CGS technique is Gauss. Gauss is operated for explaining the magnetic field’s strength. It is designated after German physicist Carl Friedrich Gauss. The character G denotes the value of the mentioned CGS techniques. Both Tesla and Gauss are used for the estimation of the magnetic induction which is applied when a particle moves through a field which is magnetic. In this tutorial, an appropriate discussion is made on the application of the CGS and Tesla techniques. Figure 1: Magnetic Field What Is Gauss? Gauss’s law represents a better understanding of the ... Read More

Introduction Celsius and Kelvin denote the two different important scales that are used to measure body temperature. Both units are used to measure the same properties but the lowest and the highest temperature are different. These two scales guide to gain the body temperature which is applicable in different calculations as well as calibrations. The standard value of the Kelvin scale starts at -273 with denotes the reciprocal of 0.0366, which is a negative value. On the Celsius scale, the point of absolute zero is 2730C while on the Kelvin scale the absolute zero is 0 k. What is the ... Read More

Introduction The bar is often used in order to express the atmospheric pressure. The atmospheric air that is often provided in millibars and the standard pressure is determined as the atmospheric pressure is denoted as 1013.25 mbar 101.325 kPa 1.01325 bars. This principle is used to state the relation between Pascal and bar, where about 14.7 pound/inch2. In this case, bar is determined as the metric unit of pressure and is not the part of SI units or the system of International Units . The bar can also be defined as the metric unit that is equivalent to 100, 000 ... Read More

Introduction If the freezing point of water gets lowered after applying a certain amount of pressure on it then this process is determined as regelation. Due to regelation ice gets melted to water at 0°C temperature under pressure and again gets frozen back to ice on the pressure removal. The glacier is considered to be the source of the river, as water in the river comes from glaciers due to the regelation of ice. On snow or ice skating is only possible due to water formation for the regelation. Here water is formed as the pressure increases and serves as ... Read More

Introduction Mass and weight both have differences and mass is a scalar quantity but weight is a vector quantity. It is seen that mass and weight are also correlated. The bodies having large mass also have a large weight. It is tough to through a large object because it has a large weight. The weight of a body is directly proportional to its mass. Here the matter is that weight of an object changes with the change of location. Definition of Mass Mass is the quantity of matter possessed by a body. It is called a scalar quantity and it ...

Introduction Mass and Volume are two important aspects of physics. The former mainly defines the amount of matter within an object’s body. The latter one is nothing but the space taken by the object. The main difference between these two aspects is that volume is the geometric value and mass is a physical value of an object. The differences between these two matters say that they have different values and both of the matters have a different state in which they react. What is Mass? Mass mainly defines the quantity of matter within a solid particle. It is considered the ... Read More

Introduction Magma and lava are two different parts of molten rocks, one that is stored on the earth’s crust and the other one emitted through the vent of a volcano. Despite both these natural components being molten rocks and both emitting from the deep down of earth’s crust, there are a few sheer differences between them in real-time. What are Magma and Lava? Magma Magma can be defined as an extremely hot semi-liquid natural component that is stored under the earth’s crust. The layered structure of the earth consists of four different layers, the inner core, the outer core, mantle ... Read More

Introduction Hydrogen is capable of having multiple isotopes at a time and deuterium appears to be one of its isotopes. It contains one neutron and one proton as its key components. Due to the presence of the neutron within deuterium, it appears heavier than the other isotopes of hydrogen. This isotope has a few real-time usages in the fusion reactors, in military and scientific fields, eventually making it one of the useful isotopes of hydrogen. What is Deuterium? Deuterium is an isotope of hydrogen that contains one neutron and one proton in its nucleus. The speciality of this isotope lies ... Read More
