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.
The fig sign is an ancient gesture with many uses. 1  Fig sign is a gesture made with the hand and fingers curled and the thumb thrust between the middle and index fingers, or, rarely, the middle and ring fingers, forming the fist so that the thumb partly pokes out. The Finger, an extended middle finger with the back of the hand towards the recipient, is an obscene hand gesture used in much of Western culture. 2  The middle finger presumably refers to an erect penis penetrating the female genetalia represented by the curled ring and index fingers.
