Yes. There are several chemical reactions that take place during the heating of the milk. Heat induced chemical reactions of milk can be classified into five groups: Acid development Precipitation of calcium phosphate Maillard reactions Casein modification and Interaction of sulphydryl groups In fresh milk all the ingredients remain in a large number of equilibria
Is the heating of milk a chemical process? Read More »
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
