According to the ideal gas law, what happens to the volume of a gas when the pressure doubles (all else held constant)?

Description : According to the ideal gas law, what happens to the volume of a gas when the pressure doubles (all else held constant)?

Last Answer : The volume is halved(Explanation): this is boyle's law PV=PV. In order to keep this equation true, if one variable (pressure in this case) is doubled, the other variable must be the reciprocal of that (in this case 1/2, which is reciprocal of double).

How many cubic meters does an elephant have?

Description : From physics we got a lot of bodies to measure to a different quantity than usual. I couldn't find the answer to this question, so I'm asking if anyone knows. I tried to derive it from human density, but it's inaccurate (it turned out that it's something around 70m3). Thanks!

Last Answer : It will be different for each elephant. The best way to find out is to dip an elephant in a full container. After pulling the elephant, you add the liquid that the elephant expelled. When topping up, you will measure carefully and thus obtain a relatively accurate volume of the elephant.
