Solution 1

To solve this problem, we can use the Clausius-Clapeyron equation, which is a way of characterizing the phase transition between two states of matter such as liquid and gas. The equation is:

ln(P2/P1) = -ΔHvap/R * (1/T2 - 1/T1)

Where: P1 and P2 are the vapor pressures at temperatures T1 and T2 res Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
