the optimum temperature for coral formation occurs where the average annual temperatures are between
Coral reef Although corals exist both in temperate and tropical waters, shallow-water reefs form only in a zone extending from approximately 30° N to 30° S of the equator. Tropical corals do not grow at depths of over 50 meters (160 ft). The optimum temperature for most coral reefs is 26–27 °C (79–81 °F), and few reefs exist in waters below 18 °C (64 °F).[46] However, reefs in the Persian Gulf have adapted to temperatures of 13 °C (55 °F) in winter and 38 °C (100 °F) in summer.[47] There are 37 species of scleractinian corals identified in such harsh environment around Larak Island.[48]
Van der Waals equation is the volume of the container occupied by each particle (not the velocity of a particle), and k is the Boltzmann constant. It introduces two new parameters: a', a measure of the average attraction between particles, and b', the volume excluded from v by one particle.
Cwm Rhondda Arglwydd, arwain trwy'r anialwch, Fi, bererin gwael ei wedd, Nad oes ynof nerth na bywyd Fel yn gorwedd yn y bedd: Hollalluog, Hollalluog, Ydyw'r Un a'm cwyd i'r lan. Ydyw'r Un a'm cwyd i'r lan Agor y ffynhonnau melus 'N tarddu i maes o'r Graig y sydd; Colofn dân rho'r nos i'm harwain, A rho golofn niwl y dydd; Rho i mi fanna, Rho i mi fanna, Fel na bwyf yn llwfwrhau. Fel na bwyf yn llwfwrhau. Pan yn troedio glan Iorddonen, Par i'm hofnau suddo i gyd; Dwg fi drwy y tonnau geirwon Draw i Ganaan – gartref clyd: Mawl diderfyn. Mawl diderfyn Fydd i'th enw byth am hyn.
