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 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?
Which is the pathway for information through a neuron?
Which is the pathway for information through a neuron? Explanation: The pathway for information through neuron are dendrite → cell body → axon → axon terminals and this because Dendrite is the input zone of nerve cell where neuron can receive information from another nerve cell. How do neurons send signals? Communication among neurons typically […]
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 […]

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 do fizzy tablets dissolve faster in hot water?
Why do fizzy tablets dissolve faster in hot water? In the hot water the tablet should have more vigorously produced bubbles than in the cold water. The higher the temperature, the faster the molecules move—and the more likely it is that the bicarbonate will contact hydrogen in just the right way for the chemical reaction […]
