PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A florist places a bouquet of white carnations in water containing blue dye. After a time, the flowers turn blue. What are the properties of water that help water travel through the stem of plants?
A
water’s ability to form crystals
B
ability of H2O to dissolve NaCl
C
cohesion and adhesion of water molecules
D
formation of covalent bonds between hydrogen and oxygen molecules
Explanation: 

Detailed explanation-1: -In this given question water sticks with the other molecules of water present in the water of the xylem of flowers. Adhesion is the other water property that allows water molecules to stick with other substance like in the given condition dye molecules sticks with water molecules.

Detailed explanation-2: -White carnation petals will turn the color of the dyed water because of capillary action within the plant.

Detailed explanation-3: -The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances. As the temperature rises, the hydrogen bonds between water continually break and reform, allowing for the overall temperature to remain stable, although increased energy is added to the system.

Detailed explanation-4: -Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances. Essentially, cohesion and adhesion are the “stickiness” that water molecules have for each other and for other substances.

Detailed explanation-5: -Three properties of a water molecule enable it to move from the root system to the leaves of the plant. They are cohesion, adhesion, and high surface tension. Water molecules are polar as they contain hydrogen bonds. Water molecules can attract one another and this is called cohesion.
