Why do a weather balloon keep increasing in volume as it rises through the stratosphere?
As it goes higher, the atmospheric pressure decreases.
The air in hot air balloon is heated to make the balloon rise?
The volume of air increases on its heating hence the balloon rises on heating
What causes a hot air balloon to rise?
Fire contacting with the air inside the balloon. The heated air within the balloon is less dense than the ambient air surrounding it, therefore for the given volume it is lighter and so rises.
How does air make a balloon fly?
air is heavier than balloon, air rises
What makes hot air balloon rise?
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.
Why do a weather balloon keep increasing in volume as it rises through the stratosphere?
As it goes higher, the atmospheric pressure decreases.
What happens to the volume or size of a balloon as it rises in the air?
The volume of the balloon will increase as it rises in the air. This is because the atmospheric pressure decreases at higher altitudes.
What will change the size of the weather balloon as it rises?
The pressure of the air inside it. The higher the balloon rises, the lower the outside air-pressure. With less pressure outside, the balloon expands because of the pressure of the air inside it. Eventually, the balloon bursts, and scientists recover the instruments when they fall to earth.
The air in hot air balloon is heated to make the balloon rise?
The volume of air increases on its heating hence the balloon rises on heating
The volume of the balloon is 3 liters at a temperature of 300 degrees kelvin What will the volume of the balloon be if the temperature rises to 350?
3.5 litre if pressure is kept constant.
A balloon carrying weather instruments is released at Earth's surface and rises through the troposphere as the balloon rises what will the instrument generally indicate?
A increase in air temperature and a decrease in air pressure
Why does a partially inflated weather balloon expand as it rises?
As height is gained the outside air pressure on the balloon is reduced. This reduction allows the gas inside the balloon to expand.
Suppose volume of 0.1 m3 and a temperature of 300 Kelvin You leave the balloon in a car with the windows rolled up and the temperature rises to 315 degrees Kelvin What is the new volume of the balloon?
0.105 m3
When a helium balloon rises in the air it expands If the volume of the balloon doubles what happens to the density of the helium inside it?
The density is reduced to 50% (half) of its original value.
In hot weather will a balloon rise higher than in cold weather?
Yes, hot air always rises while cold air sinks
Why does a balloon expand as you blow into it?
The balloon inflates because a chemical reaction occurs between the vinegar and the yeast. This generates a carbon dioxide gas (CO2).The gas rises to the mouth of the bottle and enters the balloon . The pressure is so strong that the balloon begins to inflate.
When a helium balloon rises in the air it expands. If the volume of the balloon doubles what happens to the density of the helium inside it?
The density will be 50 % from the initial value.
