Because only the rich can afford cheap batteries..... A good quality deep cycle lead acid battery will cost between $50 and $200 and, if properly maintained, will give you at least 150 deep discharge cycles.
What is the boiling point of oxygen? a. 100 degrees C c. -57 degrees C b. 8 degrees C d. -183 degrees C.
The boiling point is the temperature at which a substance changes from a liquid to a gas.    The boiling point depends on which element you are using.For instance, Wat â¦ er boils at about 100 degrees celcius; however, oxygen boils at -183 degrees celcius.ince the bonds are strong â¦ (covalent, network), diamond has a very high melting point and boiling point. Iodine does not have three dimensional network and hence has very low melting/ boiling point. It fact, it will sublime at room temperature.
