The element of value is compatible with the term luminosity, and can be "measured in various units designating electromagnetic radiation". [6] The difference in values is often called contrast, and references the lightest (white) and darkest (black) tones of a work of art, with an infinite number of grey variants in between. [6]
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. For broader coverage of this topic, see Boiling point . Boiling points, Master List format
There are two conventions regarding the standard boiling point of water: The normal boiling point is commonly given as 100 °C (212 °F) (actually 99.97 °C (211.9 °F) following the thermodynamic definition of the Celsius scale based on the kelvin) at a pressure of 1 atm (101.325 kPa).
In a cosolvent system, two miscible fluids with different boiling points are mixed to create a zeotropic mixture. [22] [23] The first fluid is a solvating agent that dissolves soil in the cleaning process. [22] [23] This fluid is an organic solvent with a low-boiling point and a flash point greater than the system's operating temperature.
Heinrich Wölfflin (German: [ˈhaɪnʁɪç ˈvœlflɪn]; 21 June 1864 – 19 July 1945) was a Swiss art historian, esthetician and educator, whose objective classifying principles ("painterly" vs. "linear" and the like) were influential in the development of formal analysis in art history in the early 20th century.

In thermodynamics, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is formed when heating a liquid consisting of two or more components. [ 1 ] [ 2 ] Given that vapor will probably have a different composition than the liquid, the bubble point (along with the dew point ) at different compositions are ...
Eastern art has generally worked in style akin to Western medieval art, namely a concentration on surface patterning and local colour (meaning the plain colour of an object, such as basic red for a red robe, rather than the modulations of that colour brought about by light, shade, and reflection). A characteristic of this style is that local ...
A form is an artist's way of using elements of art, principles of design, and media. Form, as an element of art, is three-dimensional and encloses space. Like a shape, a form has length and width, but it also has depth. Forms are either geometric or free-form, and can be symmetrical or asymmetrical.
