Could you please give an "elementary" explanation of what an endothermic process is. Remember, we are just grade 4/5/6 students. What is the reason that salt is needed in snow to make ice-cream? We know that the milk/sugar/etc. mixture freezes after snow and salt layers are put around the mixture. We also know that the snow gets almost to cold to handle, but what is the scientific explanation for this? We also know that salt is put on slippery icy surfaces to melt the ice. How is this related to the same scientific explanation as when making ice-cream?
