Gas laws 1662 Robert Boyle studied the relationship between volume and pressure of a gas of fixed amount at constant temperature. He observed that volume of a given mass of a gas is inversely proportional to its pressure at a constant temperature. Boyle's law, published in 1662, states that, at constant temperature, the product of the pressure and volume of a given mass of an ideal gas in a closed system is always constant. It can be verified experimentally using a pressure gauge and a variable volume container. It can also be derived from the kinetic theory of gases: if a container,
The miller who was a wizard, a cheat and a matchmaker parents cannot decide to whom to marry her; the mother seeks a nobleman, the father a farmer. Act II: Filimon explains to Anyuta that he has enlisted Fadei's support. Fetinia, rating Fadei's skills as a fortune-teller, asks who Anyuta's husband will be. The miller sends her on a stroll and says that it will be a gentleman, the first person she will meet on her path. (Filimon, of course). Meeting Ankudin, Fadei assures him that his daughter's husband will be a working farmer. When Fetinia and Ankudin meet they quarrel over the apparently incompatible promises given to them by the
