Introduction Measuring temperature is required in every aspect, as it is defined as a process that helps in identifying the current temperature of the respective body. In various fields, from industries of metallurgy to cooking, the temperature is being measured. However, over the years, several devices, as well as sensors, are used to conduct the…

Introduction Each Fahrenheit and Celsius scale possesses significant and different temperatures in which the water freezes and boils as well. On a centigrade scale, the temperature is expressed by pointing to degrees Celsius. On another scale, the Fahrenheit scale, the temperature is mainly expressed by pointing to degrees Fahrenheit. History and importance of both scales…

Introduction Radiation demonstrates alpha radiation (αα), neutron radiation and beta radiation (ββ). Radiation has a nucleus which carries the positive electrical charge while the electrons transmit the negative charge. The forces within the atom work towards stable and powerful balance by getting excessively rid of atomic energy or radioactivity. In this procedure, the unbalanced nuclei…

Introduction A body of matter which is confined in a particular space by the boundaries is called a thermodynamic system. They have definite permeability. According to their boundaries they may be classified as closed systems, open systems, and isolated systems. In an isolated system, there is no transformation of energy or matter across the boundaries…

Introduction You must have used the terms temperature and heat synonymously at some point in your life. That is okay because, in the context of day-to-day usage, the two terms are quite similar. A greater amount of heat is characterized by a higher temperature. However, in the realm of Physics, heat, and temperature are closely…

Introduction Tea is one of the most famous beverages in India and almost in the world. But have you ever made a cup of tea for yourself or any other? If not, then definitely you have seen at least. When the tea starts boiling then you must observe the tea leaves which were at the…

Introduction A two-stroke engine is associated with the kind of engine that utilizes internal combustion to generate a complete power cycle. The two-stroke engine completes a power cycle utilizing two strokes of the piston. Furthermore, this power cycle is completed in a single revolution of the crankshaft. These engines have a distinct property of retaining…

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…

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…

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…
