Question

Directions: Fill in the blank with the property of water described 1. You are cooking a delicious meal and attempt to pour some hot water out of the pan on the stove. Instead of pouring nicely into the sink, the water runs along the side and the bottom of the pan and ends up on the floor. really sweaty. Eventually, you start to cool down. splashing any water out. You notice that the ice always floats to the top, even 2. You just finished running a 10k in 80 degree weather. You are 3. You always put ice in your cup before adding water, to avoid though it starts at the bottom of the cup. 4 After a summer of record high temperatures and lots of sunny days, a lake is very warm. It starts to get cooler and cloudier during the fall, but the lake is still warm enough to swim in. 5. You love to add sugar to your morning coffee. 6. A water strider is able to walk or stand on the surface of water without breaking through due to the surface tension

Explanation / Answer

1. Adhesion. It is the property of water which makes it stick to different surfaces.

2. Evaporative cooling. Water on evaporation, cools down the body because water forms forms vapour by absorbing heat, thus, after heat absorption and evaporating away it cools the body.

3. Ice has low density than water because of hydrogen bonding and due to which it forms hexagonal structure. This why it floats in water.

4. Specific heat. It avoids the water cool down or warm up abruptly all of a sudden.

5. Universal solvent. Water is a polar solvent which dissolves all hydrophilic substances by hydrogen bonding and Van der waal interaction.

6. Surface tension. It is caused because of hydrogen bonding between molecules of water.

7. Barrier. Floating ice blocks other water molecules to come in contact with the chilling temperature of air, providing space for aquatic animals to live.

8. Capillary Action. The cohesion between water molecules and adhesion to tree vessels makes the water molecules travel from the root to the apex.

9. Plasma. It is the major component of blood which contains dissolved protein, sugar, and gases.

10. Cohesion. The molecules of water forms hydrogen bonds which keeps them close but allow them to flow. This hydrgen bond breaks and forms very easily.
