sand is a granular material whiwh means that it acts like both a liquid and a solid.
hence you can expect that air would be present to prove that!!
rock + water= sand
I think you mean why does hot sand heat the air by convection... The sand is heated by the sun, and the air is touching the sand, which is hot, so by convection, the sand is heating the air.
stone and air
Yes, sand has a lot of air in it. That is why when you pour water on sand, the water goes right through it.
Sand usually cools faster than air because sand has a higher thermal conductivity, meaning it can transfer heat more efficiently than air. This enables the sand to lose heat more quickly to its surroundings compared to air.
because in air there is heat and in sand its dark and cool
Modern hot air balloons do not have sand bags because the air input is easily controlled for lift. Hot air balloons used to have sandbags to weigh them down until lift off and sand was gradually dumped to gain height in the air.
A grain of sand is heavier than the same volume of air because sand has mass and air is mostly composed of gases, which have lower density and weight.
Yes, sand can contain small pockets of air between the individual grains. These pockets of air can affect the porosity of the sand, influencing its ability to hold water and impacting its overall density.
air+rock
Sand traps large particles - such as paper, stones and other foreign objects.
you add air with rock Air +Rock
