<em>Hey There!!~</em>
Which of the following describes why ice floats?
<em>Your answer is B. The density of ice is lower than that of liquid water. </em><em>Because, As the water cools, the particles slow down and the bonds last longer. These bonds cause the water molecules within ice to form a lattice-like structure that is less dense than liquid water. So, ice floats on the more dense liquid water.
</em>
<em>Why is water vital to maintaining a constant internal environment?</em>
<em>Your answer is C. It is good solvent. </em><em>It is the maintenance of a constant internal despite changes in internal and external conditions. In the human body, this includes control of:</em><em> blood glucose concentration.</em>
<em />
<em>Your answer is A. Its pH is below 7. </em><em>Because, An acidic solution is one in which the concentration of hydronium ions is greater than that of hydroxide ions. This makes the pH less than 7. An acidic solution is an electrolyte and conducts electricity.</em>
