Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
Hot air balloons use hot air. They have a burner to heat the air. Hydrogen balloons were too dangerous because hydrogen is highly flammable, even static electricity could cause an explosion. Helium is safer because helium is not flammable.
Weather balloons.
Weather balloons and satellites
Weather balloons and Doppler Radar.
Hydrogen is used in weather balloons because they are very light which help the balloon to float or fly easily.
Yes, hydrogen is lighter than air and so causes the balloon to float.
forcasting is predicting the weather. Weathering is tempering the weather
to tell u what the wether is like
to tell u what the wether is like
weather balloons are instruments that study the weather
By weather forcasting of Met. Scientists
It's equal!!
Weather Balloons play the part of METEOROLOGY AND WEATHER
the weather tomorrow is going to be cold. or the weather is forcasting 4 to 8 inches of snow or the weather is nice today
the practice of modern weather forcasting and the electomagnetic resonance
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
