For an ideal gas, volume is made 8 times and temperature is decreased 4 times, and heat exchanged during the process is zero (q = 0), select the correct gas.
Show Hint
In adiabatic processes for ideal gases, the internal energy change is purely due to the change in temperature, and noble gases like He show this behavior perfectly.
Concept:
Henry's Law states: \(P = K_H \cdot \chi\).
Taking logarithms on both sides:
\[ \log P = \log(K_H \cdot \chi) = \log \chi + \log K_H \]
This is an equation of a straight line \(y = mx + c\), where:
\(y = \log P\), \(x = \log \chi\), \(m = 1\) (slope), \(c = \log K_H\) (intercept).
Graph Analysis:
The graph of \(\log P\) vs \(\log \chi\) must be a straight line with a slope of +1 (45 degrees) and a y-intercept.
Conclusion: Option (4) (Assuming it shows a linear plot with positive slope).
