PV=nRT
if you are fixing PV and T then the question really is how many moles of Helium is 16 g. Take that number of moles and multiply by the molecular weight of Nitrogen (28.02 g/mol) to get the number of grams of N2 needed.
16 g/4.00g per mol = 4 mol He X 28.02 g/mol = x g of N2 needed.
the pressure is 1.73289 ATM (atmospheres)
3.5 litre if pressure is kept constant.
Temperature, Pressure, and humidity.
The higher the temperature, the higher the pressure and vice versa. When the temperature rises the gas molecules move faster and hit the balloon more often and with more energy.
Decrease the pressure of the surrounding environment. Thus, the force acting on the balloon from the outside decreases, allowing the air pressure that creates a force inside the balloon to have less of a counteracting force.
Liquid nitrogen has a low temperature, and that obviously decreases the volume of the air inside the balloon. The balloon shrinks
The balloon full of air is basically at room temperature, and this includes the balloon itself and the gas (the air) inside it. When we douse the balloon with liquid nitrogen, it cools the heck out of the air inside, and when we cool air, it's volume decreases. Cool it a lot, and its volume decreases a lot. That's why the balloon shrinks when the liquid nitrogen is poured over it.
The higher the temperature, the higher the pressure and vice versa. When the temperature rises the gas molecules move faster and hit the balloon more often and with more energy.
the pressure is 1.73289 ATM (atmospheres)
It does affect a nitrogen balloon.
assuming the balloon is closed, the air pressure would double
A weather balloon gathers information on temperature, atmospheric pressure, humidity, and wind speed.
3.5 litre if pressure is kept constant.
This depends on the mass of nitrogen contained in the balloon.
Temperature, Pressure, and humidity.
The higher the temperature, the higher the pressure and vice versa. When the temperature rises the gas molecules move faster and hit the balloon more often and with more energy.
The liquid is so cold that the air particles in the balloon almost stop moving, which causes the balloon to shrink. When the balloon is taken out of thr liquid the particles regain speed and expand inside of the balloon.
