What is the process of polymerization?
What is the process of polymerization? Polymerization is the process to create polymers. These polymers are then processed to make various kinds of plastic products. During polymerization, smaller molecules, called monomers or building blocks, are chemically combined to create larger molecules or a macromolecule. What type of reaction is polymerization? Polymerization reactions are chain reactions, […]
How do you calculate the coefficient of friction?
How do you calculate the coefficient of friction? The formula to calculate the coefficient of friction is μ = f÷N. The friction force, f, always acts in the opposite direction of the intended or actual motion, but only parallel to the surface. How Do You Measure V belt tension? How to Measure V Belt Tension […]
What kind of reaction occurs when chemicals enter the bloodstream?
What kind of reaction occurs when chemicals enter the bloodstream? A “systemic” reaction occurs when chemicals enter the bloodstream through the skin, eyes, mouth, or lungs. What is it called when a chemical enters the bloodstream? Injection is the fourth way chemicals may enter the body. While uncommon in most workplaces, it can occur when […]

What rocks is coarse grained?
What rocks is coarse grained? Coarse grain varieties (with mineral grains large enough to see without a magnifying glass) are called phaneritic. Granite and gabbro are examples of phaneritic igneous rocks. Fine grained rocks, where the individual grains are too small to see, are called aphanitic. Basalt is an example. What are the most common […]
Why different objects kept on a table at room temperature do not exchange heat with table?
Why different objects kept on a table at room temperature do not exchange heat with table? Answer. Answer: The sense of touch allows us to recognise temperature differences of objects in the same room which we could easily assume should all be at that same room temperature. The temperature of an object is dependant on […]
What is the effect of pressure in change of state of matter?
What is the effect of pressure in change of state of matter? Changes in presure have very little effect on the volume of a liquid. Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the […]
