A weather ballon with a 2 meter diameter at ambient temperature holds 525 grams of helium. what type of electric probe could be used to determine the pressure inside the ballon?

To determine the pressure inside the weather balloon, you would need an electric probe that is capable of measuring atmospheric pressure. One commonly used device for measuring pressure is a barometer. However, a traditional barometer might not be suitable for measuring the pressure inside the balloon while it is inflating or when it is at higher altitudes.

A more appropriate option would be a digital or electronic barometer known as an electronic pressure sensor. These sensors can be designed to measure air pressure accurately and precisely. They are frequently used in meteorological applications, including weather balloon experiments.

Here's how you could use an electronic pressure sensor:

1. Choose an electronic pressure sensor that has the necessary pressure range to cover the expected pressure values inside the weather balloon. Ensure that the sensor can handle the required accuracy and resolution.
2. Carefully attach the sensor to the weather balloon. This can be done by using a suitable mounting technique or by integrating the sensor into the balloon structure during the manufacturing process.
3. Connect the sensor to an appropriate data acquisition system or instrumentation device capable of reading the sensor's output. This could be a computer, a data logger, or a dedicated pressure measurement device.
4. Calibrate the pressure sensor before use to ensure accurate pressure readings. This calibration process involves exposing the sensor to known reference pressures and adjusting its output to match the actual pressure values.
5. Once the weather balloon is inflated, the pressure sensor will continuously measure and provide real-time pressure data. Monitor the readings to determine the pressure inside the balloon accurately.

By employing an electronic pressure sensor, you can obtain precise measurements of the pressure inside the weather balloon throughout its flight, enabling detailed analysis and scientific research.
