The critical temperatures of NH3, He, O2, and N2 are 405.5K, 5.3K, 154.3K and 126K respectively. If the samples of these gases are cooled from 298 K, which one will liquify first? 1 point

Answer:NH3
Explanation:
Since H2, O2, andN2 have very low force of attraction among their molecules, these gases cannot liquefied. But molecular force of attraction is high in NH3. So it can be liquefied easily.
