What you should first understand is thermodynamics ... in the most simplistic terms ...
Pressure * Volume / Temperature is constant
so if the gas cools ... then Pressure1 * Volume1 / High Temperature is smaller than Pressure2 * Volume2 / Low Temperature
Let's firstly assume* that the pressure will be constant so Volume1/big number Volume2/smaller number => Volume 1 > Volume 2 ...hence the volume of gas when the temperature drops should be smaller.
*(though in reality pressure drops as you go higher in the atmosphere)
** To be realistic, the pressure outside the balloon will be smaller than the pressure when the balloon was at ground level, causing it to expand... to find out with a certain degree of certainty (the elasticity of the balloon is not really constant) how much "bigger" it will be, you need to also know the exterior pressure.
I would recommend learning more about thermodynamics as the law slightly differs with the type of transformation that occurs (adiabatic, isotropic etc )
Later Edit *** oh and I think its actually helium ... if you were referring to the fact that the gas should turn liquid because of the low temperatures then no ... helium and hydrogen boils at a very low temperature (below -200 Celsius).
/ btw sorry for any grammar mistakes, English is my second language.
You get two charged balloons, which both stick to the wall but repel each other.
When you blow between two balloons, the airflow causes them to move towards each other. This is due to the increase in velocity and decrease in pressure between the balloons, resulting in a net force pushing them together.
When two balloons both have a negative charge, they will repel each other due to the like charges. The negative charges on each balloon will create an electrostatic force that pushes the balloons away from each other.
When light passes through a hydrogen cloud in the universe, the hydrogen atoms can absorb certain wavelengths of the light. This absorption can create dark absorption lines in the spectrum of the light, revealing information about the composition and temperature of the cloud.
When two balloons are rubbed with a sock, they become charged with static electricity. When brought close to each other, the like charges repel each other, causing the balloons to push away from each other due to the electrostatic force.
Becomes lighter and rises, the principle of hot air balloons.
Helium is completely inert, it is the most inert of all elements, and so it will not react in any way with hydrogen (or with any other element). So, if you mix hydrogen and helium, nothing happens. You have a mixture of hydrogen and helium. It's a lot lighter than air, you can make balloons that will float. Of course, you can do that with pure hydrogen or with pure helium, as well.
Each hydrogen atom has 1 electron. When two hydrogen atoms combine they each share that electron with the other hydrogen atom, creating a covalent bond and a molecule of H2.
Ammonium chloride is thermally decomposed in ammonia and hydrogen chloride.
repel
After weather balloons are released into the atmosphere, they ascend to high altitudes, collecting data on temperature, humidity, and pressure. Eventually, the balloons burst due to low air pressure, and a parachute deploys to slow their descent. The instruments attached to the balloon are then retrieved for analysis of the gathered data.
they pop
stuff happens Hydrogen atoms need nearly 30 kT to be torn apart This happens on the surface of the sun We can tell this from the line spectra
At 20 degrees Celsius, hydrogen remains a gas as it has a boiling point of around -253 degrees Celsius. At this temperature, hydrogen molecules continue to move independently and do not form any distinct structure.
Hydrogen does not react with water
They Repel.
