Thermometer Reading Temperature
Introduction Thermal energy is a form of energy which generates due to heat and flows from the higher amount of temperature to the lower amount of temperature in the body on contact. It is possible to measure the thermal energy in the body with the utilisation of the “sum of kinetic energies”. “Joule” (J) is…

Refrigerator Heat Pump
Introduction The refrigerant is usually put through a compressor that gradually raises the gas pressure and enhances the temperature. Then through the ”condense coils” the hot gas flows to heat up the inside area which is of higher temperature. If the freezer or refrigerator’s temperature is kept at zero degrees Fahrenheit then the food will…

Differences Between Enthalpy and Entropy
Introduction Thermodynamics is a study that establishes a relationship between heat and work. To understand it well, the concept of two terms- entropy and enthalpy has to be deeply dug in. In this article, the basic definitions of entropy and enthalpy, as well as the differences will be discussed in an ordered way. In very…

Adiabatic Process
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,…

Cyclic Process
Introduction Let us take a container containing air and start heating that container. Let the initial temperature and pressure of the air 25°C and 1 atmospheric pressure, respectively. After heating for some time, the temperature of the air will become 100°C and the pressure of the air 2 atmospheric pressure. So the temperature and pressure of the…

Difference Between Centre of Gravity and Centroid
Introduction Centroid is the term that applies to a geometrically balanced figure or an object. It is the center of that figure or object. The methods to find the center of a symmetrical entity differs, but it exists, and there is no confusion about that. For example, a triangle has the centroid which is the…

Einstein Field Equation
Introduction The immense importance of Einstein Field Equations (“EFE”) warrants a thorough understanding of every single element contained within them. Einstein’s equation is another name for the Einstein Field Equation. Ten equations make up this set which is derived from the General Theory of Relativity of Albert Einstein. This tutorial aims to present a tight,…

Difference Between Density and Specific Gravity
Introduction Whenever we do some work experiment with water or any liquid, we observe that some objects are immersed in water whereas some float over it. For example, ice cubes float on water. Because ice cubes are less dense than water. But if we put a stone in water it will sink. Because stone is…

Static Friction
Introduction There are numerous kinds of friction out there and one such friction is static friction which tends to keep an object in a state of rest. This friction is faced by people when they try to put the body in a state of motion over a surface. This force however does not trigger a…
