Step-by-step explanation:
The most important state of matter for the survival of human beings is liquid because it plays a vital role in maintaining bodily functions. The human body is approximately 60% water, and water is essential for numerous physiological processes. It helps regulate body temperature, transports nutrients and oxygen, lubricates joints, and aids in digestion and waste elimination.
Additionally, water is crucial for maintaining the integrity of cells and tissues. It serves as a medium for chemical reactions within the body and ensures proper hydration, which is vital for overall health and wellbeing. Without an adequate supply of liquid water, humans would be unable to survive.
