Question

6 multiple choice 1 point the unique properties of water enable life to exist on earth. which of these is a property of pure water? it dissolves many substances. it is slightly more acidic than air. its solid form is more dense than its liquid. it has a low heat absorption capacity.

Explanation:

1. Analyze the first option: Water is a universal solvent and can dissolve many substances (like salts, sugars, etc.). This is a well - known property of pure water.
2. Analyze the second option: Pure water has a neutral pH (around 7), and air is not acidic in the same context. So pure water is not more acidic than air.
3. Analyze the third option: The solid form of water (ice) is less dense than liquid water, which is why ice floats on water.
4. Analyze the fourth option: Water has a high heat absorption capacity (high specific heat), which helps in regulating temperature.

Answer:

A. It dissolves many substances.
