Why do hot air balloons have sand bags?
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.
Why is mud more likely than sand to fossilize an organism?
Mud is more likely than sand to fossilize an organism because mud has finer particles that can fill in cavities and preserve details of the organism's structure. In contrast, the looser nature of sand may not provide the same level of protection and support for fossilization.
How can sand be effectively used as insulation in construction projects?
Sand can be effectively used as insulation in construction projects by creating a layer of sand between two walls, which helps to trap air and reduce heat transfer. The small particles of sand create pockets of air that act as insulators, preventing the loss of heat or cold. This method is cost-effective and environmentally friendly, providing thermal insulation for buildings.
What makes sand squeaky?
Sand can make a squeaky sound when small air pockets between the grains are compressed as you walk on it. The friction between the grains of sand rubbing against each other can also create a squeaky noise.
Is sand an element compound mixture solution suspension or colloid?
Sand is made form a mixture of mineral grains (mainly quartz or calcite) which are themselves compounds. If there is water or air flowing though the sand at a fast rate, then it can also be a suspension.
How do you create sand in Doodle God 2?
rock + water= sand
Why is hot sand heats the air convection?
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.
How do you make sand little alchemy?
stone and air
Does sand have alot of air in it?
Yes, sand has a lot of air in it. That is why when you pour water on sand, the water goes right through it.
Does sand or air cool faster?
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.
Why the ice cube melts faster in air but not in sand?
because in air there is heat and in sand its dark and cool
Why do hot air balloons have sand bags?
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.
What is heavier a grain of sand or 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.
How do you sand in Alxemy?
air+rock
How make sand Alxemy?
you add air with rock Air +Rock
Why is hot sand heats the air an example of convection?
Hot sand heating the air is an example of convection because the heated sand warms the air directly above it, causing the air to expand and rise. As the warm air rises, cooler air moves in to take its place, creating a continuous cycle of heat transfer through the movement of the air. This process is known as natural convection.
What are beaches made out of?
of sand,air,and acid
