Frigorific mixture

A frigorific mixture is a combination of substances that, when mixed together, produces a cooling effect. This effect is typically achieved through an endothermic reaction, where the mixture absorbs heat from its surroundings, resulting in a drop in temperature. Common examples of frigorific mixtures include: 1. **Salt and Ice**: When salt is added to ice, it lowers the freezing point of the ice, causing the ice to melt and absorb heat from the environment, resulting in a cold mixture.
