For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant. If volume increases, then pressure decreases and vice versa, when temperature is held constant.
Yeah, except when it's not. The two fingers held aloft in a V are fine provided your palm is facing out, but in some countries -- namely, Australia, New Zealand, and the United Kingdom -- it's an insult of the first order if you make the same gesture but with your palm facing inward.
Answer Wiki. Not really. People sign one-handed all the time, usually when they're carrying something, or just when they're lazy. Sign language uses a dominant and a non-dominant hand; the non-dominant hand is usually used for supportive actions, and if this is the arm that is broken, it's fairly easy to continue using it this way while in a sling.
