47) I think when you are measuring the temperature of a substance you are looking at<span> average energy of the molecules that composes a substance.- I think
48) Three fossil fuels are, natural gas, coal and oil
I guess what could differentiate them is that: </span>Coal is a solid fossil fuel formed over millions of years by decay of land vegetation. When layers are compacted and heated over time, deposits are turned into coal. Whereas Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor and gas like oil, it is formed from the remains of marine microorganisms.<span>
So the difference could be how they are formed

Yuri [45]

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.

The Prostate gland

The prostate is a walnut-sized organ that surrounds the first part of the urethra. It is located between the bladder and the penis. Semen is formed by the prostate by combining a thick white fluid it initially produced with the sperm from the testicles. It also produces an antibiotic protein known as prostate-specific antigen (PSA) that changes the semen into liquid.
