A snowman, glass of water and steam might look very different but they are made of the same stuff! Just like any substance, water can exist in three different forms, called states: solid, liquid and gas. The state will change when the substance is heated. As a solid, a substance has a fixed volume and … Read more
Last Updated: March 19, 2026 at 11:48 pmThe second law of thermodynamics states that the entropy of an isolated system never decreases because isolated systems spontaneously evolve towards thermodynamic equilibrium—the state of maximum entropy. Equivalently, perpetual motion machines of the second kind are impossible. The second law is an empirically validated postulate of thermodynamics, but it can be understood and explained using … Read more

Last Updated: September 23, 2018 at 6:48 pmSound wave is one of the most recognizable characters from the original Transformers line. He had an alternate mode – a microcassette recorder – and possessed a distinctive monotone, computerized voice. Soundwave is able to identify and jam transmissions across the entire energy spectrum, a talent that makes him suited to his position as Decepticon … Read more

Last Updated: March 19, 2026 at 11:48 pmSound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing. Sound also travels through plasma. Sound Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. (Sound can propagate through solids … Read more

Last Updated: September 23, 2018 at 6:48 pmSpeed Of Sound The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one … Read more
