The temperature of the sand rose because energy was created. It's like rubbing your hands together to warm them up. There's friction and there's new energy, meaning more heat, and higher temperature.
You need to disconnect the pump and filter from the pool lines first, 2nd if you have you owners manual check to see how much sand you need to have to replace the old sand, if you do not have that info then you need to put the old sand in buckets to figure out how much needs to go back in its always good to have an extra bucket of sand, 3nd remove the bolts from the top of the filter and take the lid off there should be a gasket underneath the top lid try not to tear it if you do get, a new one the torn one will leak, remove the old sand, once you get the old sand out by what ever means meaning using a running hose, you are then ready to put the new sand in. The trick hear is, there should be a seprator that goes inside of the filter to put the sand in the right place, if you do not have this, do not take the filter apart you will only make a mess of the pool, you need this seprator, go to the pool store and get or order one, this seprator goes down inside of the middle of the filter and all you do is pour the sand in around the outer part of the filter until the desired amount of sand is put back into the filter, then remove the seprator, put the gasket back on the top of the filter place some bolts between the top of the lid gasket and filter place the rest of the bolts tighten put the filter and pump and pool lines back together prime the pump just like starting it up at the start of the season make sure you connections are tight and you are not sucking any air.
If you stirred water and sand together, you would have a mixture of water and sand until the sand sinks to the bottom.
The density of sand varies depending on what minerals the grains of sand are made of, and wet sand is denser than dry sand. As a rough rule of thumb, a litre of dry sand weighs about 1500 grams.
In denser medium,particles of matter are very close to each other.whereas,in rarer medium,particles of the medium are slightly farther apart.
coarse sand, medium sand, fine sand, very fine sand, silt, & clay
sand is simply sand there is not much nourishment that a plant can get from sand and it does not hold water well. Soil can be a mixture of sand clay decaed bio materials and serves as a nourishing medium for plants as wel as being capable of holding water, worms bacteria and algae also find it an easier medium to live in.

Distribution of soil particles for identifying the type of soils ie., wherther it is well graded or uniform graded or poorly graded soil.And also fine sand, medium sand coarse sand or fine gravel, medium gravel, coarse gravel etc.
Medium is the stuff the Sculptor using to make the piece. It could be clay, Styrofoam, paper, sand or any material that you can sculpt.
The sand at our beach is mostly quartz rock. It is a medium grain sand and is suitable for barefoot walks. On hot days watch out, it may burn your feet.
It will depend on type of sand ie fine,medium,coarse one cu mt per ton of sand will range between 1.4 ton to 2 ton
To go slow, or not try.
Thermal Conductivity (W/m K) of >Coarse SAND (dry) is 0.25 >Medium SAND (dry) is 0.27 >Fine SAND (dry) is 0.15 See: b-dig.iie.org.mx/BibDig/P10-0464/pdf/2952.pdf
The answer depends on the grain size, lithology, moisture content, and level of compaction of the sand. Generally, one cubic ft of clean (no silt/clay), dry, fine to medium sand that has been compacted to a dense, non-yielding condition will weigh about 110 lbs., while a loose fine to medium sand will weigh about 100 lbs. per cubic foot.
