Meteorologists use weather balloons to carry weather instruments high into the atmosphere. When it is first released at Earth’s
surface, a weather balloon typically appears underinflated. What happens to the balloon’s volume as it rises into the atmosphere? Explain your answer in terms of pressure.
The pressure of the gas used in the weather balloon increases to expand the balloon.
Explanation:
Weather balloons contain the boxes where the weather measurement instruments are present that is attached to the large balloon.
Weather balloon uses gases like Hydrogen or Helium. When the weather balloon rises to the atmosphere, the air pressure decreases. This leads to the increase in the pressure of hydrogen or Helium gas used in the weather balloon. This expands the balloon.
The gas particles hits the balloon container and generates the pressure. The increase of pressure thus helps the weather balloon to move in a constant speed through the atmosphere.
