Based on the calculations, the pressure of this gas sample at 27°C is equal to 0.17 atm.
<h3>How to determine the final pressure.</h3>In order to calculate the final pressure of an ideal gas at constant volume, we would apply Gay Lussac's law.
Mathematically, Gay Lussac's law is given by this formula;
<u>Where:</u>
- P is the pressure.
- T is the temperature.
- k is the constant of proportionality.
Substituting the given parameters into the formula, we have;
Final pressure = 0.17 atm.

The volume of the base of the region enclosed by the parabola is; V = 9
<h3>Integral Volume of a Solid</h3>The length of each cross-section is determined by the horizontal distance (parallel to the x-axis) from one end of the parabola to the other.
Thus;
y = 3 - 2x²
Making x the subject gives us;
x = ±√[(3 - y)/2]
Thus;
The horizontal distance is;
√[(3 - y)/2] - (-√[(3 - y)/2])
⇒ 2√[(3 - y)/2]
The area of each cross-section is simply the square of the section's side length, so the area would be;
A = (2√[(3 - y)/2])²
A = 6 - 2y
Thus, volume is;
V =
Solving this gives V = 9
