To determine which gas, ammonia (NH3) or carbon dioxide (CO2), will liquefy first when cooling from 500 K to their respective critical temperatures, we can follow these steps: ### Step 1: Identify the Critical Temperatures - The critical temperature of ammonia (NH3) is 405.5 K. - The critical temperature of carbon dioxide (CO2) is 304.10 K. ### Step 2: Understand the Concept of Critical Temperature - The critical temperature is the highest temperature at which a substance can exist as a liquid. Above this temperature, no amount of pressure can liquefy the gas. ...
