Question

If an ice cube and a scoop of table salt are left outside on a warm, sunny day, why does the ice cube melts and the salt doesn’t

Answer 1

Ice is a crystalline form of water, which only contains hydrogen and oxygen atoms. The molecules of water form loose bonds with each other, and only a modest amount of heat (latent heat of fusion) is necessary for the crystal lattice of ice to break down into liquid water. The molecules of sodium chloride have a much higher latent heat because the crystal lattice is much more robust. The melting point of salt is around 800̊̊̊̊̊̊̚℃, whereas water is 0℃.

Answer 2

because the salt isn't a liquid nor can't be turned into one unless it is put in a solution nor can it be melted by the suns heat from the earths distance/location
