Nitrogen fixation is a process in which nitrogen (N2) in the Earth's atmosphere is converted into ammonia (NH3). Atmospheric nitrogen or molecular dinitrogen (N2) is relatively inert: it does not easily react with other chemicals to form new compounds.
The pH scale measures the concentration of how acidic or basic something is. The lower the number below 7, is acidic. Above 7 is basic. 7 is waters purest form.

Answer:
65 L
Explanation:
It is assumed that the temperature is constant at both the sea level and the altitude.
<em>According to the gas law, at constant temperature, the pressure of a gas is inversely proportional to its volume.</em> Mathematically:
P1V1 = P2V2 where P1 = pressure at initial volume, V1 = volume at initial pressure, P2 = pressure at final volume, and V2 = volume at final pressure.
In the illustration, V1 = 15 L, P1 = 100 kPa, V2 =?, P2 = 23 kPa
V2 = P1V1/P2 = 100 x 15/23 = 65.22 L
<u>The volume of the hot air balloon at the altitude would be 65 L</u>
