What is weather balloon device for measuring air pressure temperature and relative humidity called?
A+ Radiosonde
A balloon carrying weather instruments is released at Earth?
Temperature, Pressure, and humidity.
How does a weather balloon help meteorologist?
1. It can be used to work out wind speed and direction at a range of heights. (This can be done by tracking the balloon by radar or by assuming a rate of ascent and using triangulation). By using in-built sensors... 2. It measures air temperature at a range of heights. 3. It measures humidity at a range of heights. (This becomes less accurate with height, because it starts off measuring humidity with respect to water, but at height the water is all frozen, so the humidity is with respect to ice)
How many sensors are on a weather balloon?
Three (3) sensors. One (1) for barometric pressure. One (1) temparature. One (1) for humidity.
Does helium contract in cold weather and cause a helium balloon to sink and if warmed will it rise again?
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain

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 is a weather balloon job?
A weather balloon gathers information on temperature, atmospheric pressure, humidity, and wind speed.
A balloon carrying weather instruments is released at Earth?
Temperature, Pressure, and humidity.
What are you measuring when you are measuring pressure?
When you are measuring air pressure, you are measuring the force that the air is exerting outwards, on whatever you are using to compress it (since materials resist being compressed). For example, measuring the air pressure in a balloon is measuring the amount of force that the air is pushing against the material of the balloon. This is usually expresed in Pounds per Square Inch (PSI).

Can you measure air pressure in a party balloon?
The air pressure inside the balloon will be slightly higher than outside. This is because the air inside the balloon is slightly compressed by the elasticity of the membrane of the balloon itself. By way of illustration, if you inflate a balloon, don't tie it and just let it go, then to everyones' amusement at parties the balloon flies crazily around the room until it is fully deflated! This fun aspect of balloons occurs as a result of the higher pressure inside the balloon escaping from the balloon to join the air in the room that is at normal pressure. Actually measuring the pressure inside the inflated balloon would require an experiment where the volume of pressurised air in the inflated balloon could be measured by a) measuring the volume of pressurised air inside the balloon by fully immersing the inflated balloon in a measuring receptacle full of water (with normal atmospheric pressure in the room pressing down on the surface of the water) and, then b) measuring the volume that the pressurised airinside the balloon would occupy once outside the balloon at normal atmospheric air pressure by inverting the measuring receptacle full of water (whilst held in a larger shallow tank of water so as to keep the measuring receptacle full of water once inverted - in the usual physics lab manner) and then release the air from the balloon into inverted water-filled measuring receptacle where it would gather in the top of the same. The difference in the two volumes would directly correlate with the difference in air pressure inside and outside the balloon.
If a balloon filled with an unknown gas floats in the air then what can be said about the gas in the balloon?
The gas in the balloon is lighter than air. It has a specific gravity relative to air of less tha one.
What is a weather balloon?
Weather balloons typically carry a thermometer (to measure air temperature), a psychrometer (to measure humidity), a barometer (to measure air pressure) and a transmitter (to send the information through radio waves to equipment at the ground so we will know what the instruments are measuring up in the air)
How do you make it harder for a balloon to pop?
You deflate it, thus increasing the relative thickness of the rubber.
