The Etymology of Slang Sexual Terms. The word horny sexually excited, lecherous derives from an interesting yet not surprising source. As early as the mid-18th century, an erection was known as a horn or the horn, simply because it looked a bit like one.James Joyce even used the term in his Ulysses.he word horny sexually excited, lecherous derives from an interesting yet not surprising source.

Charles' Law. Statement. For a fixed mass of gas at constant pressure, the volume is directly proportional to the kelvin temperature. That means, for example, that if you double the kelvin temperature from, say to 300 K to 600 K, at constant pressure, the volume of a fixed mass of the gas will double as well.
The gas evolved from the reaction is collected by attaching one end of a hose to the reaction container and inserting the other up into the inverted gas collection bottle. As the gas is created, it will displace water from the bottle.The volume of gas can be determined by the amount of water that was displaced by the gas. The volume of gas collected and the gas laws can be used to calculate the number of moles of gas collected.his equation can be used to calculate the pressure of the gas collected. Once the pressure of the collected gas is known, the number of moles of gas can be calculated using the ideal gas law: PV= nRT. Where: 1  P = Pressure of the gas. 2  V = Volume of water displaced. 3  n = number of moles of gas. 4  R = the ideal gas constant.
