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 Given Note The Given Note The Given Note is the fourth solo album by master uilleann piper and prominent Irish traditional musician Liam O'Flynn. Produced by Shaun Davey and recorded at Windmill Lane Studios in Dublin, the album was released in 1995. The title was suggested by O'Flynn's good friend Seamus Heaney, winner of the 1995 Nobel Prize for Literature. Heaney also wrote a tribute to O'Flynn which is on the sleeve notes of the album. In his review for Allmusic, Chris Nickson gave the album three out of five stars, calling it "an object lesson in the way [Celtic] music should
