Question

The pressure of a hydrogen balloon is 100.4 kPa. The balloon

floats away into the troposphere where the atmospheric
pressure is 95.6 kPa. What is the positive difference between
the pressure in the balloon and the pressure of the
troposphere in atm?
atm

Answer 1

0.0474 atm

Step-by-step explanation:

Hello!

In this case, since the pressure inside the balloon is greater than that of the troposphere, the positive pressure difference is given by:

`\Delta P=100.4kPa-95.6\\\\\Delta P=4.8kPa`

Now, since 101.325 kPa = 1 atm, the pressure in atm would be:

`4.8kPa*(1atm)/(101.325kPa)\\\\=0.0474atm`

Best regards!
