Boyle’s Law
Compressibility is an outstanding characteristic of gases. The English scientist, Robert Boyle, was among the first to study this characteristic. He called it the springiness of air. He discovered that when the temperature of an enclosed sample of gas was kept constant and the pressure doubled, the volume was reduced to half the former value. As the applied pressure was decreased, the resulting volume increased. From these observations he concluded that for a constant temperature the product of the volume and pressure of an enclosed gas remains constant. This became Boyle’s law, which is normally stated: The volume of an enclosed dry gas varies conversely with its pressure, provided the temperature remains constant.
You can demonstrate Boyle’s law by confining a quantity of gas in a cylinder which has a tightly fitted piston. Then apply force to the piston so as to compress the gas in the cylinder to some specific volume. If you double the force applied to the piston, the gas will compress to one half its original volume.
Changes in the pressure of a gas also affect the density. As the pressure increases, its volume decreases; however, there is no change in the weight of the gas. Therefore, the weight per unit volume (density) increases. So it follows*…show more content…*

The acceleration, if any, is directly proportional to the force. It is inversely proportional to the mass of the body. This law can be explained by throwing a common softball. The force required to accelerate the ball to a rate of 50 ft/sec2 would have to be doubled to obtain an acceleration rate of 100 ft/sec2. However, if the mass of the ball were doubled, the original acceleration rate would be cut in half. You would have 50 ft/sec2 reduced to 25 ft/sec2. Do not confuse mass with weight. This law can be explained mathematically (A = acceleration; F = force; M = mass) A =

1347 Words | 6 PagesThe universe is said to have consist with patterns, that since we were born, humans’ complex brains are taught and trained habitually to rapidly observe and perceive to match patterns and arrangements with the information given, whether they really exist or not. In fact, a large number of tasks that our brain processes daily is seeking patterns. There are no limits when we seek for patterns, even when there are no signs presented. This is for the human brains to learn, to observe, to measure, to
