Yes, sand has a lot of air in it. That is why when you pour water on sand, the water goes right through it.
Alot Lol
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
Well sure just follow your dreams, and buy alot sand.
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.
alot.
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.
Alot of dollars and not very many grains of sand.
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.
"There is a lot of sand" is correct.There is alot of sand makes more sense.
