What are the objects float in air?
Objects that float in air are typically those that are less dense than the air around them, such as helium balloons or lightweight objects like feathers. These objects are able to displace enough air to generate an upward force greater than the force of gravity acting on them, allowing them to float.
What gas does make a balloon float?
Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.
What makes balloons float when they are full of air but not float when they are deflated?
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
Why do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Why do bubbles float?
Bubbles float because they are filled with gas that is lighter than the surrounding air. This causes them to rise and float on the surface of liquids or in the air.
What are air sacks used for in pollen?
Air sacs in pollen are used for buoyancy, enabling the pollen to float through the air and be carried by wind or pollinators to reach other flowers for fertilization. This helps increase the chance of successful pollination and reproduction for the plant.
Why do pollen grains have air-sacs?
Pollen grains have air-sacs to help them float in the air and be carried by wind or insects for pollination. The air-sacs provide buoyancy and allow the pollen grains to be dispersed more effectively to reach other flowers for fertilization.
Is the average number of pollen grains in a cubic meter of air called the pollen rate?
No, the average number of pollen grains in a cubic meter of air is typically referred to as pollen concentration or pollen count, not pollen rate. The pollen rate could refer to the speed at which pollen is released or spread in the air.
How hot air baloons are able to float?
hot air baloons are able to fly because the hot air that is released in to the ballon wants to get out so there for it keeps pushing and that is how a hot air balloon floats
What are the objects float in air?

These objects are able to displace enough air to generate an upward force greater than the force of gravity acting on them, allowing them to float.
What characteristics does a fire have?
Being hot, being light and able to float in the air, and it's a vapor.
Which part of the flower is released into the air?
pollen
The average number of pollen grains in a cubic meter of air is known as the?
Pollen Rate.
Is The average number of pollen grains in a cubic meter of air is called the air rate?

Does any train float on air?
No a train does not float in the air, no train does.
"In the pine family with air bladders, what purpose do the air bladders serve"?
The air bladders in the pine family with air bladders help with pollen wind dispersal. The pine family with air bladders has the bladders to help the pollen being blown into the female cones of the conifer.
What would happen if pollen grains could not float in the air?
If pollen grains could not float in the air, they would have difficulty traveling long distances to reach other plants for pollination. This could lead to reduced genetic diversity, decreased reproduction rates, and ultimately, smaller plant populations. It may also disrupt ecosystem dynamics that rely on cross-pollination for species survival.
