Not really, you need a lot of heat (pure quartz melts at about 1780 C). If you add some other stuff (like lead, sodium oxides, calcium oxides) you can lower the melting point considerably.
Sand doesn't melt ice to any noticeable degree. However, sand picks up heat from sunlight better than pure ice, which can speed up melting a little bit.
No, sand does not melt at 300 degrees Celsius. Sand, primarily made of silicon dioxide, has a melting point of approximately 1,700 degrees Celsius. At 300 degrees, sand would not melt but may undergo some physical changes like expansion or decomposition depending on its composition.
Sand is an extremely efficient filter for anything
Salt
it turns into sand
The subject is bolt.Of lightning is a prepositional phrase that supplements the subject, can melt is the verb, and sand is the direct object.
It depends on the temperature of the sand and the ice! Sand does not dissolve in water to any significant extent, so that mixing sand with ice will not lower the melting point of the ice. If there is a sufficient amount of sand and it has a temperature above the freezing point of water, sand will eventually melt ice by heat conduction from the sand to the ice. If the sand has a lower temperature than the ice, mixing them will never produce melting of the ice.
Sand abosorbs light better then ice. So the heat melts the ice.
only rock salt does, not sand. if this is not right im sorry!
Salt
maybe it will melt
salt. its tasteyer
