mar 05, 2020 mixing of iron filings and sand is a physical change, as they just mix with each other without the need of a chemical reaction. burning of a candle is also a physical change, as the flame causes the wax to melt down.,is mixing sand in gravel a physical or chemical change,mar 14, 2014 its a physical change, but not much of one because gravel is hard, mixing it with sand doesnt damage the gravel. wiki user. 2014-03-14 044414. this answer is helpful.
multimedia filtration is a modern physical water treatment technique that uses at least three different layers of filtration media, typically anthracite, sand and garnet, to filter water. this filter arrangement allows for larger particulates to be trapped at the top of the filter while smaller particulates are trapped deeper in the media.,whats the story with sand,of weathering physical, chemical and biological. physical weathering does not affect the chemical makeup of the rock and it just changes the size of pieces. it can be caused by tumbling of rocks such as in a river or by the freezethaw cycle of water. chemical weathering is caused by a chemical reaction between rocks and water or water
