actually its D) movement of tectonic plates
Answer: I think it's a don't blame me if it's wrong though
Explanation:
The corret answer is D
The pressure in the flask is 3.4 atm.
<em>pV</em> = <em>nRT </em>
<em>T</em> = (20 + 273.15) K = 293.15 K
<em>p</em> = (<em>nRT</em>)/<em>V</em> = (1.4 mol × 0.082 06 L·atm·K⁻¹mol⁻¹ × 293.15 K)/10 L = 3.4 atm
