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.
Hand. To dream of your hands says a lot about your current mood and emotion, but in particular it shows how you are connected with others and how you impact the world. The right hand represents strength and activity; it shows the human masculine side. The left hand represents the gentle side with generosity and femininity. In a dream you might see yourself holding hands with someone - this reflects your attachment to that person and the will to keep them close to you at all times. Dreaming of bleeding or injured hands represents a blow to your pride.
