You can heat fresh milk at 140 °C around 10 min. If you keep heating coagulation will occurs. It happens due to the aggregation of the milk proteins. Milk contains 85-88 % of water depending on the source animal and rest of them are solids. Usually cow’s milk solid contains lactose (4.9%), fat (3.4%), protein

Never add water in concentrated acid in an open beaker. Add concentrated acid into water. Acid loves water. The moment you will add water into acid, the acid molecules will try to grasp it and it might spill over you. Always use hand gloves, eyewear, and proper PPE when working with HCl or other acid.

Polymer electrolyte membrane fuel cells, also known as proton exchange membrane fuel cells (PEMFCs) are believed to be the most promising type of fuel cell for electric vehicles. The PEM fuel cell was invented by Willard Thomas Grubb and Leonard Niedrach in the early 1960s where sulfonated polystyrene membranes were used for electrolytes. In 1966, sulfonated polystyrene

Anthelmintics are therapeutic agents used to destroy parasitic worms or remove them from the infected host. Commercially available anthelmintics belong to one of three chemical classes-benzimidazoles, macrocyclic lactones or imidazothiazoles.1 All the anthelmintics work in a similar fashion; they prevent absorption of sugar from infected hosts, necessary for the worm’s survival. Helminths: Parasitic worms Common
