A Complete Guide to learn Science, Biology, Physics and chemistry with simple explanation. This app provides the best study material for all the beginners and expert level students who want to learn science.
Learn Science
Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Scientific methodology includes the following: Evidence. Experiment and/or observation as benchmarks for testing hypotheses.
Learn Biology
Biology is the study of life. The word "biology" is derived from the Greek words "bios" (meaning life) and "logos" (meaning "study"). In general, biologists study the structure, function, growth, origin, evolution and distribution of living organisms.
Learn Biology is a natural science discipline that studies living things. It is a very large and broad field due to the wide variety of life found on Earth, so individual biologists normally focus on specific fields. These fields are either categorized by the scale of life or by the types of organisms studied.
Learn Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
The science of the behavior of the physical world. Stemming from the Greek "physis," which means the characteristics of nature, physics covers the structure of matter (atoms, particles, etc.) and a huge variety of subjects, including chemical bonding, gravity, space, time, electromagnetism, electromagnetic radiation, the theory of relativity, thermodynamics and quantum mechanics.
Learn Chemistry
The branch of natural science that deals with the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules is called chemistry.
Chemistry is one branch of science. Science is the process by which we learn about the natural universe by observing, testing, and then generating models that explain our observations. Because the physical universe is so vast, there are many different branches of science.
Thus, chemistry is the study of matter, biology is the study of living things, and geology is the study of rocks and the earth. Mathematics is the language of science, and we will use it to communicate some of the ideas of chemistry.
Learn Science is the field, that is, it develops a body of knowledge by observing things and performing experiments. The meticulous process of gathering and analyzing data is called the "scientific method,".

Thermal engineering
Thermal engineering is a specialized sub-discipline of mechanical engineering that deals with the movement of heat energy and transfer. The energy can be transferred between two mediums or transformed into other forms of energy.
Aspects of thermal engineering
Thermal engineering involves thermodynamics, liquid mechanics, and heat and mass transfer. This knowledge is important when operating almost any machine. Systems experience heat buildup from mechanical elements and electric circuits. This heat, if not redirected, can damage the system. Thermal engineers work to design the inclusion of fans or liquid circulators to regulate the internal temperature of the device. Computers and car batteries are two examples of this principle in action.
Thermal engineering focuses on the transfer of heat, fluid mechanics, and heating and cooling systems, such as those used in the electric power industry, the automobile industry and the heating, ventilation and air conditioning (HVAC) industry. Thermal engineers design systems that utilize various thermal sources of generated energy to create chemical, mechanical or electrical energy. They must have an understanding of thermodynamics, fluid mechanics and heat and mass transfer.
Heat transfer and mass transfer
Thermal engineers study heat transfer, which concerns the creation, utilization, conversion and exchange of heat between systems. Heat transfer is divided into several mechanisms, including:
Heat conduction: Also called diffusion, heat conduction is the direct exchange of kinetic energy of particles between two systems when one system is at a different temperature from another or its surroundings.
Heat convection: Heat convection involves the transfer of mass from one area to another. It occurs when the bulk of a fluid transfers heat as matter within the fluid moves.
Thermal radiation: Thermal radiation is heat transfer by electromagnetic radiation without the need for matter to be present between systems. Sunshine is a good example of radiation.
How does thermal engineering work?
Many processing plants use machines that utilize heat transfer. The thermal engineer is responsible for ensuring the right amount of energy is transferred for the machine's operation. Too much energy and the components could overheat and fail. Too little energy and the whole machine could shut down.
