A watt-second (symbol W s or W⋅s) is a derived unit of energy equivalent to the joule. [34] The watt-second is the energy equivalent to the power of one watt sustained for one second . While the watt-second is equivalent to the joule in both units and meaning, there are some contexts in which the term "watt-second" is used instead of "joule ...
Sunlight also drives most weather phenomena, save a few exceptions, like those generated by volcanic events for example. An example of a solar-mediated weather event is a hurricane, which occurs when large unstable areas of warm ocean, heated over months, suddenly give up some of their thermal energy to power a few days of violent air movement.
Although notation was partly standardized, style and symbol varied between alchemists. Lüdy-Tenger [1] published an inventory of 3,695 symbols and variants, and that was not exhaustive, omitting for example many of the symbols used by Isaac Newton. This page therefore lists only the most common symbols.

The International Junior Science Olympiad (IJSO) is an annual science competition for students aged 15 and under on December 31st of the competition year. It is one of the International Science Olympiads and an international academical competition that covers physics , chemistry and biology at the same time.
The International Science Olympiads are a group of worldwide annual competitions in various areas of the formal sciences, natural sciences, and social sciences.The competitions are designed for the 4-6 best high school students from each participating country selected through internal National Science Olympiads, with the exception of the IOL, which allows two teams per country, the IOI, which ...
Enthalpy (/ ˈ ɛ n θ əl p i / ⓘ) is the sum of a thermodynamic system's internal energy and the product of its pressure and volume. [1] It is a state function in thermodynamics used in many measurements in chemical, biological, and physical systems at a constant external pressure, which is conveniently provided by the large ambient atmosphere.
