When sand is brought near a balloon, it may be attracted to the balloon due to static electricity. This is because the balloon can become negatively charged by rubbing it against certain materials, causing it to attract the positively charged sand particles.
To lift a heavier load off the ground, the pilot can increase the temperature of the air inside the balloon by using the burner. As the air inside the balloon heats up, it becomes less dense than the cooler air outside, creating lift and enabling the balloon to rise with the heavier load. Additionally, the pilot can adjust the amount of ballast on board to help control the ascent.
grains of sand will stick together when wet because of the property of water known as cohesion. cohesion occurs because the water molecule will become attracted to the sand because water will become polarized
Scattering sand on icy roads can help increase traction for vehicles by providing a rough surface for tires to grip onto. The sand creates friction between the tires and the road, helping to prevent slipping and sliding on the icy surface.
if you mean a small balloon like those of birthdays, they can be filled with normal air like your breath or it can be filled with helium gas, as it's lighter than air and balloons will be floating in air and if you mean balloons like huge ones used in trips and so on, they are also filled with helium but there's also heat generator to make helium more lighter thus increase the height to which your alloon float
The wind carrying sand grains deposits the sand when the wind's velocity decreases, or when an obstacle interrupts the wind flow. This causes the heavier sand grains to settle and accumulate, forming sand dunes.
the sand would stand up
To bring a hot air balloon lower, the pilot can release hot air by pulling a cord that opens the top of the balloon envelope, allowing the heat to escape. This causes the air inside the balloon to cool down, which decreases the overall lift and brings the balloon closer to the ground.
The sand washes back straight down the beach
one is in the sand. you have to draw a balloon. another is in the ice you must bring down onto the river.
I believe the word you're looking for is Ballast.
As the sandbag is dropped from the hot air balloon, the overall mass of the system (balloon + sandbag) decreases. This causes the average density of the system to lower, leading to a buoyant force greater than the gravitational force acting on the system, resulting in the balloon rising.
Dump it in water. Pepper floats, sand sinks. This works but you can also try using a balloon. Fill the balloon with air then rub it on your hair. Then move it around slowly over the mixture the pepper will cling to the balloon and the sand will not.
you turn into sand
What happens when sand or salt is used in place of the liver
Nothing happens when backing soda and sand are mixed. There is no reaction.
By using heavy weight sacks of sand
you get salty sand water
