Solution:

Subsequently, the weather balloon has a diameter of 65 liters at 28.0 and 748 mmHg. We are told to calculate the diameter of the weather balloon, whether the pressure increases to 385 mm Hg and the temperature decreases to –15.0 C.

Remember that the ideal gas law is as follows:

PV = nRT

The density, volume and temperature of the gas are related to the number of moles of the gas and the constant of the fundamental product:

PV / T = nR

The value of the nR is unchanged. In the case of a given gas mole, the original and final pressure, volume and temperature of the gas shall be calculated by the combined gas law:

P1V1 / T1 = P2V2 / T2
