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 Frogs Who Desired a King The Frogs Who Desired a King The Frogs Who Desired a King is one of Aesop's Fables and numbered 44 in the Perry Index. Throughout its history, the story has been given a political application. According to the earliest source, Phaedrus, the story concerns a group of frogs who called on the great god Zeus to send them a king. He threw down a log, which fell in their pond with a loud splash and terrified them. Eventually one of the frogs peeped above the water and, seeing that it was no longer moving, soon all hopped upon it and
