What are the five properties of alkalis? Chemical Properties of Alkalis Alkalis react with Acids to form salt and water. This reaction is called neutralisation reaction. Alkalis react with ammonium salts to form salt, water and ammonia gas. Alkalis react with solution of metal salt to form another metal salt and hydroxide. What are the […]
What is difference between preventive and periodic maintenance?
What is difference between preventive and periodic maintenance? The main difference between the two is that preventive maintenance is scheduled at regular intervals while predictive maintenance is scheduled as needed (based on asset conditions). These costs are often acceptable to organizations that have already successfully implemented a preventive maintenance program. What are the benefits of […]
What is form according to Plato?
What is form according to Plato? In basic terms, Plato’s Theory of Forms asserts that the physical world is not really the ‘real’ world; instead, ultimate reality exists beyond our physical world. The Forms are abstract, perfect, unchanging concepts or ideals that transcend time and space; they exist in the Realm of Forms. Did Plato […]
Is the only source of heat and light?
Is sweating sympathetic or parasympathetic?
Is sweating sympathetic or parasympathetic? We need sweating to control body temperature; water evaporating from the skin cools the body. Sweating is under the control of the sympathetic nervous system, which orchestrates the body’s reaction to stressful situations and emergencies—sometimes called the “fight or flight” response. How do emotions affect the autonomic nervous system? The […]
Is heat needed in chemical change why?
Is heat needed in chemical change why? Chemical reactions involve the production of new materials which are quite different from the reacting substances. Any new materials come from the reacting substances. While heat is often necessary to initiate a chemical reaction it is not always necessary. Chemical reactions are used to produce most of our […]

What is the 7 Universal Laws? To name them, they are the Laws of Mentalism, Correspondence, Vibration, Polarity, Rhythm, Cause and Effect and Gender. Once you understand, apply and align yourself with these seven Universal Laws, you will experience transformation in every area of your life beyond what you have ever dared to imagine. What […]
What is the origin of frictional force?
What is the origin of frictional force? Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Friction originates in nanoscale contacts, as the result of new surface formation. The theory explains the generation of frictional force and frictional heating in dry contact. What energy does friction produce? When friction […]
Why does the filament in a light bulb glow more brightly when an electric current is slowly increased?
Why does the filament in a light bulb glow more brightly when an electric current is slowly increased? 4.As the electric current in a lightbulb is slowly increased, the filament glows more and more brightly. Why does this happen? As the current increases, the electrons more frequently bump into more atoms of the resistor (filament) […]
