What is the Internal energy — is one of the most important concepts in physics that we face in elementary school. Understanding this concept helps us uncover the basics of thermodynamics and heat transfer, and also explains the phenomena that occur in our daily lives.
What is the essence of internal energy?
This is a type of energy that is associat Number List with the movement and interaction of individual material molecules. Internal energy is the sum of kinetic energy (motion energy) and potential energy (interaction energy). It determines the thermal telegram data state of the substance and depends on factors such as temperature, pressure and volume.
Internal energy may change in the process of heat transfer or work. For example, when we put a hot teapot on the table, energy passes from boiling water in the teapot to the table, while the internal energy of the system (chain + boiling water) decreases. Also, internal energy can change when we do the work, for example, lifting the load or twisting the handle of a bicycle.
Knowl Number List ge of internal
Energy helps us understand the reasons for the changes in its state and makes it possible to delve deeper into the laws of physics. In addition, this concept is us Number List in many areas of science and technology, including tips to increase customer loyalty heat transfer, energy and technology.
