Enthalpie de changement d'étatEn thermodynamique, l'enthalpie de changement d'état (anciennement chaleur latente de changement d'état) d'un corps pur est par définition la variation d'enthalpie qui accompagne un changement d'état du corps rapportée à la quantité de matière mise en jeu lors de cette transformation. Par exemple pour le passage de l'état liquide à l'état de vapeur on parlera denthalpie de vaporisation.
Glacier ThwaitesLe glacier Thwaites est un glacier d'Antarctique situé dans la Terre Marie Byrd. Il forme une barrière de glace alimentée par un courant glaciaire permettant à une partie des glaces de l'inlandsis Ouest-Antarctique de s'évacuer du plateau antarctique occidental vers la mer d'Amundsen.
Physics educationPhysics education or physics teaching refers to the education methods currently used to teach physics. The occupation is called physics educator or physics teacher. Physics education research refers to an area of pedagogical research that seeks to improve those methods. Historically, physics has been taught at the high school and college level primarily by the lecture method together with laboratory exercises aimed at verifying concepts taught in the lectures.
Heat strokeHeat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than , along with red skin, headache, dizziness, and confusion. Sweating is generally present in exertional heatstroke, but not in classic heatstroke. The start of heat stroke can be sudden or gradual. Heatstroke is a life-threatening condition due to the potential for multi-organ dysfunction, with typical complications including seizures, rhabdomyolysis, or kidney failure.
