Pressure

Question 1

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 and pressure as it rises into the atmosphere? Check all that apply.

Revolt · Accepted Answer

The pressure in the balloon decreases.; The volume of the balloon increases.
