mple Exercise 11.5 Practice Exercise 1-Enhanced-with Feedback 24 of 32> ou may want to reference (Pages 456-459) Section 11.6 while completing this problem Part A Interpreting a Phase Diagram Based on the phase diagram for methane below, what happens to methane as it is heated from 250 °C to 0 °C at a pressure of 10 atm? 102 Supercritical fluid 102 Liquid 10 Solid 10-1 Gas 10-4 -200 -100 100 Temperature C) O It condenses at about-200 C O It reaches the triple point at about -200 C O It boils at about-200 C It melts at about-200 It sublimes at about-200 C

Explanation / Answer

At a pressure of 10^(-2) atm with the change in temperature from -250C to 0C, the methane gas converts directly from solid into gas

Hence the correct answer must be Option E (It sublimes at about -200C)
