Interpretation:
The diameter of the spherical hydrogen filled balloon needs to be calculated, if the balloon and balloonist together weigh 168 kg and if the temperature is 22 0C and pressure is 758 mm Hg.
Concept introduction:
According to the
When gases are placed at two different conditions, then to determine the changed variable, combined gas law is used. Below is the formula of combined gas law:
Here,
- P1 and P2 are the pressure of gases
- V1 and V2 and volume of gases
- n1 and n2 number of moles
- T1 and T2 are the temperature of gases
Formula to calculate the density is:
Here d is the density, MM is the molar mass of gas, P is pressure, R is gas constant and T is temperature.
And the formula to calculate the volume of sphere =
