Yes
Yes, it can. Just as helium balloon will.
Helium is lighter than air and a balloon filled with helium may rise up.
Because helium is lighter than air. So helium balloon will rise up.
The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)
Yes
False
Yes, it can. Just as helium balloon will.
So the blimp will stay aloft/still adn will float.
Helium
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
Helium is lighter than air. so balloons filled with helium will float in air
Helium Buoyancy--- This is the same thing that allows boats to float on water. The boat displaces a volume of Water and if the weight of the Boat is lighter than the weight of the displace water, then it floats. This is same with Blimps or Dirigibles. The Blimp is filled with Helium. The volume of the helium inside the blimp is lighter than the weight of the voume of air that it displaces so it rises. When the blimp reaches the higher altitude where the air is thinner (and therefore lighter) then the blimp will stop rising. At this altitude the weight of the blimp EQUALS the weight of the air it displaces.
Helium
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
Helium is lighter than air.
Because helium is lighter than air.
