Why only iron attracted towards magnet and not the sand?
Iron contains magnetic domains that align in the presence of a magnetic field, creating a magnetic attraction. Sand, on the other hand, does not contain magnetic properties like iron, so it is not attracted to a magnet.
How do you use sand in Minecraft?
Sand can be used to make glass, sandstone and TNT. Glass is made by smelting the sand in a furnace. Sandstone is a block that looks quite similar to sand. But sandstone does not fall down when you remove the block beneath it, which is often useful when creating houses and other buildings. It can be crafted by placing 4 sand blocks in a square, like this (S = Sand, E = Empty): E E E S S E S S E TNT isn't so commonly used. It's not very useful, and hard to make. But it can be fun sometimes. When you activate it, it explodes a little area around it. It can be crafted like this (S = Sand, G = Gunpowder/Sulphur): G S G S G S G S G

Does pool sand wear out and need to be changed?
Yes it does. I've replaced my sand twice in 12 years. But I know others who have not. Depends on the amount of debri it has to remove and what type. I have too many nearby trees. I knew my sand was finished when the back pressure got so high it blew out the skimmer basket when it turned off. Replacing the sand takes a couple of hours. Good luck. Sand needs to be replaced every three to five years. Proper backwashing and treatment with a sand revitalizer will keep your filter working efficiently throughout the sand's useful lifecycle.

What are the uses of sand bath in the chemistry lab?
Sand baths are commonly used in chemistry labs for gentle and uniform heating of glassware and reactions. They provide a stable temperature environment for reactions that are sensitive to rapid changes in temperature. Sand baths are especially useful for heating flammable or volatile materials since they eliminate the risk of direct contact between the heating source and the material being heated.
How do you separate sand from sulfur?
One way to separate sand from sulfur is by using a physical method called filtration. You can mix the sand and sulfur with water to dissolve the sulfur, and then filter the solution to separate the sand particles from the sulfur solution. The sulfur solution can then be evaporated to recover the sulfur.
