Properties Of Water
Words: 1189 / Pages: 5 .... has a boiling point of 100 degrees C and a
freezing point of 0 degrees C. The amount of energy needed to raise the
temperature of one gram of water by one Celsius degree is called a Calorie. One
Calorie is about twice as much energy as you need to warm one gram of most other
fluids by the same amount. This makes water much better for regulating the
temperatures of animals and the environment.
Water also has a very high heat of vaporization. Converting one gram of
cold water into ice requires 80 Calories of energy. Converting the same amount
of very hot water into steam requires 540. The high amounts of energy required
to change water from .....

Nuclear Energy: Uranium Fission
Words: 1142 / Pages: 5 .... MJ/kg
(Energy 27). Those numbers alone are astounding.
Uranium is also abundant, thanks to recent discoveries of large reserves.
At present, uranium is only being mined and separated from ore. However, a
huge untapped source is our oceans. Sea water contains 3.3x10^(-9) (3.3 parts
per billion) of uranium, so the 1.4x10^18 tons of sea water contains 4.6x10^9
tons of uranium. All the world's electricity usage, 650GWe could therefore be
supplied by the uranium in sea water for 7 million years(Energy 25). This is a
only a theoretical number because it is not possible to get all of the uranium
out of our vast oceans. Also, it does not incl .....

Cancer Treatments And Breakthroughs
Words: 1572 / Pages: 6 .... completely gone. They're too small to see, so doctors can't tell if they have taken it all out or not. So, just to be sure, doctors usually take out a lot of the healthy tissue surrounding the area. This could damage the person's system and their appearance. Also, cancer sometimes forms around structures that can't be taken out, like an organ. In these cases, surgery alone is basically useless. Radiation therapy is another option, and many doctors prefer this in many cases. When a patient receives radiation therapy, gamma rays are sent in to treat the region that the tumor is in. Patients usually receive five to eight weeks of treatments every day, .....

Acid deposition kill fish, soil bacteria, and as well as aquatic and terrestrial
plants. the acid also drain the soil of essential nutrients such as aluminum and
releases them into bodies of water such as streams, lakes, and ponds. These
bodies of water develop highly concentrated l .....
