What is an advantage of water?
A) It remains liquid over a relatively large range of temperature
B) It has a large surface tension, thus allowing the formation of droplets
C) It consists of polar molecules, thus allowing the dissolution of organic material
D) All of the above
E) None of the above
To determine the advantage of water, let's go through each option and explain the relevance of each:
A) It remains liquid over a relatively large range of temperature: This is true since water has a high boiling point and a low freezing point compared to other liquids. This property allows water to exist as a liquid over a wide range of temperatures, which is crucial for sustaining life and various processes on Earth.
B) It has a large surface tension, thus allowing the formation of droplets: Surface tension refers to the force that holds the molecules on the surface of a liquid together. Water has a relatively high surface tension, which enables it to form droplets. This property is important for various natural phenomena, such as the formation of raindrops and the ability of insects to walk on water.
C) It consists of polar molecules, thus allowing the dissolution of organic material: Water is a polar molecule, meaning it has a partial positive charge on one end and a partial negative charge on the other. This polarity allows water to dissolve other polar molecules, including many organic substances. The ability to dissolve organic material is crucial for various biological processes, such as digestion and the transport of nutrients within the body.
Considering the explanations for options A, B, and C, it is evident that all of them are advantages of water. Therefore, the correct answer is D) All of the above.
