At normal temperature and atmospheric pressure, ______ has a density of 1.87 kg/m3, which is 1.5 times heavier than air and exists as a liquid below the critical temperature of 31°C.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. carbon dioxide.
At normal temperature and atmospheric pressure, carbon dioxide (CO2) has a density of 1.87 kg/m3, making it 1.5 times denser than air. Below its critical temperature of 31°C, carbon dioxide exists as a liquid. This property is utilized in various industrial applications, such as refrigeration and carbonation processes. Carbon dioxide's density plays a crucial role in its behaviour and applications, influencing its movement and interactions within different environments and systems.
