Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
There are properties associated with water that support life on earth. Which of the following best describes two of these properties?
A
It takes a great deal of energy to change the state of water; water can dissolve most compounds
B
It takes the presence of a solute to cause water molecules to form hydrogen bonds; water is adhesive
C
It takes little energy to change the state of water; water molecules can form ionic bonds with each other
D
It takes the absence of water for most chemical reactions to occur; water can change temperature quickly allowing for changing conditions
Explanation: 

Detailed explanation-1: -We will examine four emergent properties of water that con-tribute to Earth’s suitability as an environment for life: cohe-sive behavior, ability to moderate temperature, expansion upon freezing, and versatility as a solvent. Water molecules stay close to each other as a result of hydro-gen bonding.

Detailed explanation-2: -The four unique properties of water that make it unique are high specific heat, high polarity, adhesion cohesion, and a lower density as a solid.
