Answer:
Yes, with change in humidity, enthalpy changes as well.
Explanation:
This can be explained by the given relation:
H =
where
H = enthalpy (in Btu/lb)
w = specific humidity (lb-water/lb-dry air)
= dry-bulb temperature (in
)
The above relation clearly explains that if temperature does not vary, enthalpy is in direct proportion with the humidity.
So, any change in humidity results in a corresponding change in the enthalpy.
Answer : The volume of the balloon at the new location is, 591.3 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.995 atm
= final pressure of gas = 0.720 atm
= initial volume of gas = 500 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
Therefore, the volume of the balloon at the new location is, 591.3 L
