Volume is simply worked out by weight divided by density. So in this case that means 13.558 / 0.089 = about 152 litres. There are equations linking the three.
V (volume) W (weight) D (density)
V * D = W
W / D = V
W / V = D
Hope that helps.
To find the volume of the balloon, divide the mass of hydrogen by its density: 13.558 g / 0.089 g/L = 152.15 L. Therefore, the volume of the balloon is 152.15 liters.
152.34g/mL
152.34 g/mL
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
Contemporary weather balloons are usually filled with helium. Helium is lighter than air, and this allows the balloon to rise as this gas is lighter than air.Hydrogen would also work as it has a low density, like helium. And hydrogen is a bit cheaper than helium because it can be "made" from water. But hydrogen is flammable or even explosive, and it is generally not used for that reason.
To enable the gases inside the balloon to expand which they do when the balloon reaches high altitudes. At this point the balloon becomes much larger.
A digital barometer or a pressure transducer could be used to determine the pressure inside the weather balloon. These devices are capable of measuring the pressure exerted by the gas inside the balloon and can provide accurate readings.
Generally, its higher temperature. The temperature of a rising magma is generally higher than the temperature of its surrounding rocks. Because of its higher temperature, it is also lighter compared to the surrounding rocks (it has a lower density), so it rises. Imagine a hot air balloon: it rises because the air inside the balloon is heated, heating the air lowers its density (makes it lighter). As long as the density of the air inside the balloon is lower than the density of the air outside the balloon, the balloon rises.
Hydrogen
Inside a balloon there is gas. This gas is normally helium if you want the balloon to fly high, but hydrogen also works.
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
due to pressure inside the balloon, will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.

There is the fire that changes the density of the inside of the balloon causing it to rise.
The density is reduced to 50% (half) of its original value.
With helium filled balloons, they rise upwards as the gas inside is of a lower density than the atmosphere around them. The balloon will continue to rise and the gas inside it will expand as the atmospheric pressure decreases with increasing altitude. Eventually, the gas inside the balloon will expand enough to burst the balloon and the balloon will fall back to the ground. When and where this happens depends on weather conditions, air temperature, the rubber used in the balloon, etc.
A hot air balloon works by heating the air inside the balloon envelope using a burner. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can control the altitude of the balloon.
To enable the gases inside the balloon to expand which they do when the balloon reaches high altitudes. At this point the balloon becomes much larger.
The density will be 50 % from the initial value.
