Why a helium weather balloon expands as it rises in the air. assume that the temperature remain constant.?

When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand.
The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.

How many air particles are in a balloon?
That depends on how big the balloon is and weather or not it is inflated with air.
Why the pipes broke during the freezing cold weather?
water expands when frozen.
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.
'hydrogen is used in weather balloons Explain what happens to the volume of gas in the if the air temperature falls?
What you should first understand is thermodynamics ... in the most simplistic terms ... Pressure * Volume / Temperature is constant so if the gas cools ... then Pressure1 * Volume1 / High Temperature is smaller than Pressure2 * Volume2 / Low Temperature Let's firstly assume* that the pressure will be constant so Volume1/big number Volume2/smaller number => Volume 1 > Volume 2 ...hence the volume of gas when the temperature drops should be smaller. *(though in reality pressure drops as you go higher in the atmosphere) ** To be realistic, the pressure outside the balloon will be smaller than the pressure when the balloon was at ground level, causing it to expand... to find out with a certain degree of certainty (the elasticity of the balloon is not really constant) how much "bigger" it will be, you need to also know the exterior pressure. I would recommend learning more about thermodynamics as the law slightly differs with the type of transformation that occurs (adiabatic, isotropic etc ) Later Edit *** oh and I think its actually helium ... if you were referring to the fact that the gas should turn liquid because of the low temperatures then no ... helium and hydrogen boils at a very low temperature (below -200 Celsius). / btw sorry for any grammar mistakes, English is my second language.
How does a hot air baloon work?
Simply put, the weather balloon is a lighter-than-air vehicle or aerosonde that provides lift to an instrument package to get it to altitude. The instruments thus situated can collect data which, when combined with other information from both similar and different sources, can be used to assess current conditions, and, as an extension, to forecast weather.

What is a weather balloon job?
A weather balloon gathers information on temperature, atmospheric pressure, humidity, and wind speed.
How does rainfall weather a rock?
because of the constant water hitting it until it expands then burst.

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.
A balloon carrying weather instruments is released at Earth?
Temperature, Pressure, and humidity.
What woul happen to the volume of the 100L weather balloon if its temperature increases from 25 C TO 125 C while the external pressure remain constant?
The universal gas equation is PV = nRT (Pressure x Volume = Number of moles x Universal Gas Constant x Temperature in Kelvin/Rankin). So - if Pressure is constant, the number of moles is constant, but the temperature increases from 25C (298 K) to 125C (398K) - a 34% increase, a similar 34% increase in volume will occur.
What weather balloon device for measuring air pressure temperature and relative humidity is called a?
A+ Radiosonde

What unit does a weather balloon measures?
A weather balloon is sent up to gather information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring unit called a radiosonde.
What does a weather balloon do?
A weather balloon floats in the atmosphere to gather clue about weather all over the world.
