What is under relaxation factor? The under relaxation factors ensure that the solution from one step to the next does not change too much as it then might get unstable. So with very low under-relaxation factors the solution from one step to the next changes only very little which usually leads to a stable solution […]

What elements are produced only in supernova explosions? The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium.

When esters undergo hydrolysis under acidic conditions what two products are formed? Ester hydrolysis is a reaction that breaks an ester bond with a molecule of water or a hydroxide ion to form a carboxylic acid and an alcohol. One common use of ester hydrolysis is to create soaps, which are the salts of fatty […]

Which are examples of negative feedback? Examples of processes that utilise negative feedback loops include homeostatic systems, such as: Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low) What are examples of […]

What do you mean by distribution coefficient? In the physical sciences, a partition coefficient (P) or distribution coefficient (D) is the ratio of concentrations of a compound in a mixture of two immiscible solvents at equilibrium. Hence the partition coefficient measures how hydrophilic (“water-loving”) or hydrophobic (“water-fearing”) a chemical substance is. What are the limitations […]
