Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.
Answer:
Hurricanes are large, swirling storms. They produce winds of 119 kilometers per hour (74 mph) or higher. That's faster than a cheetah, the fastest animal on land. Winds from a hurricane can damage buildings and trees.
tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.
Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth.
A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.
Wildfires are fires that burn out of control in a natural area, like a forest, grassland, or prairie. They often begin unnoticed. They spread quickly, and can damage natural resources, destroy homes, and threaten the safety of the public and firefighters. Humans cause most wildfires.
