Why does temperature remain constant during a change of state? The temperature remains constant during the change of state because the heat energy which is supplied to change the state of matter is used in breaking the intermolecular forces and other attractive forces. Hence the temperature remains constant as all the heat is used up […]

What are the major spheres of the earth?
What are the major spheres of the earth? These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air). Each of these four spheres can be further divided into sub-spheres. What is the purpose of the atmosphere? The atmosphere is made of gases that are essential […]
What is the difference between a step-up transformer and a step down transformer Brainly?
What is the difference between a step-up transformer and a step down transformer Brainly? A transformer that increases voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer. Conversely, a transformer designed to do just the opposite is called a step-down transformer. How are the step-up transformers […]
