![]() Leeks turned brown when cooked at temperatures between 110 ☌ and 160 ☌ (230 ☏ and 320 ☏) because of the caramelization process. If the temperature is further increased to 100 ☌ (212 ☏) and they are cooked for too long, they become rubbery. It is important to note that the cooking temperature for eggs needs to reach at least 65 ☌ (150 ☏) to kill potential Salmonella.Īt the temperatures between 70 ☌ and 73 ☌ (158 ☏ and 165 ☏) the eggs set. Proteins contained in the egg whites require a higher temperature to set and as a result, the egg whites set at higher temperatures than the yolks. The latter is a Japanese breakfast dish, served with the traditional breakfast meal, and often accompanied by rice, miso soup, grilled fish, and pickled vegetables. Examples include the “65-degree egg” also known as a soft-boiled egg, and “onsen tamago”, which means “hot-spring egg” in Japanese. Some recipes call for the eggs to be cooked at this temperature range to produce the semi-liquid texture for the yolk and the slightly more liquefied texture for the white. EggsĪt the interval between 63 ☌ and 65 ☌ (145 ☏ and 150 ☏), the eggs start to coagulate and become thicker. This egg was cooked at a temperature range between 63 ☌ and 65 ☌ (145 ☏ and 150 ☏). In some cases, mountaineers use small pressure cookers, which artificially increase the pressure, and thus - the boiling point. This change in the boiling point temperature makes it necessary to increase cooking times, otherwise, the foods may be undercooked. For example, water boils at 71 ☌ (160 ☏) at an elevation as high as the top of Mount Everest (8,848 meters or 29,029 feet). The temperature for the boiling point decreases by 1 ☌ for every 285 meters (or 935 feet). Mountaineers encounter lower atmospheric pressure when ascending high mountain peaks, and can watch water boil at lower temperatures there. Atmospheric boiling point for water is 100 ☌ (212 ☏). Atmospheric melting point for ice is 0 ☌ (32 ☏). Most people know the temperature ranges for different states of water, both in liquid form and in crystallized form as ice. For example, liquids may evaporate below the boiling point. While the temperature intervals for the solid, liquid, and gaseous stages are usually specific for each given substance, phase changes can occur even within these temperature intervals. ![]() Mount Kinabalu on the island of Borneo, Malaysia. Water boils at lower temperatures at high altitudes. This is called a critical point, and the substance is said to be a supercritical fluid. If the pressure and temperature are sufficiently high, then the substance reaches a state where it behaves the same in a liquid and a gas form. The melting point is called atmospheric melting point. For this special case, the boiling point is called normal (or atmospheric) boiling point. The temperature intervals for each state as well as the melting and boiling points are dependent on pressure, and often the quoted temperatures are for atmospheric pressure at the mean sea level. The temperatures at which the crystals of given substances liquefy and liquids evaporate are called melting point and boiling point, respectively. ![]() Phase Changeįor every material, there exists a temperature interval for which it is in a solid state, another interval for which it is in a liquid state, and finally an interval for which it is a gas. There are many more examples of the importance of temperature intervals, but this article will focus on the latter two. In natural substances and materials keep their state constant within a given temperature interval, and undergo phase changes if the temperature increases or decreases. In cooking, foods are temperature-treated, to change their flavor and to make them safe, and the temperature interval determines the outcome of the cooking process with regards to safety, texture, flavor, etc. In climatology, for example, temperature intervals for a given month or season are monitored, to determine any short-term and long-term changes in the climate patterns for a given region. Temperature intervals have a range of applications in everyday life and science. Similarly, the interval of 100 ☌ is equivalent to an interval of 180 ☏, so the temperature from 0 ☌ to 100 ☌ will rise in Fahrenheit scale from 32 ☏ to 32 + 180 = 212 ☏. This means that if the temperature is raised from 0 ☌ to 5 ☌, on the Fahrenheit scale, it will raise from 32 ☏ to 32 + 9 = 41 ☏. For example, in the temperature converter 5 ☌ = 41 ☏, but in this temperature interval converter, the interval of 5 ☌ is equivalent to an interval of 9 ☏. This converter for temperature intervals is different from the converter for just the temperature in that it provides information on what a given interval in one scale converts to on another scale.
