Why Does Rock Salt Make Ice Colder? | Sciencing

Why Does Rock Salt Make Ice Colder? | Sciencing

The molecules are in constant motion, however, vibrating and moving around each other ceaselessly. When you lower the temperature, the molecules slow down, and because they have less energy, they start sticking to each other. At the freezing point, the energy of movement is so low that the molecules coalesce into a solid structure.

How Does Temperature Affect the Rate of Reaction? | Sciencing

How Does Temperature Affect the Rate of Reaction? | Sciencing

The effect of temperature on rate of reaction is just one of the things that can affect how a reaction proceeds, that is, how quickly whatever reactants are present become transformed into products. Of course, many of these factors are active at all times and can have competing influences on the overall rate of a given reaction.
