Liquid metal will wet to most metallic surfaces. Specifically though, room-temperature liquid metal can be very reactive with certain metals. Liquid metal can dissolve most metals; however, at moderate temperatures, only some are slightly soluble, such as sodium, potassium, gold, magnesium, lead, nickel and mercury. Gallium is corrosive to all metals except tungsten and tantalum, which have a high resistance to corrosion, more so than niobium, titanium and molybdenum. Similar to indium, gallium and gallium-containing alloys have the ability to wet to many non-metallic surfaces such as glass and quartz. Gently rubbing the alloy into the surface may help induce wetting. However,
Room temperature and the Japanese Pharmacopeia defines "ordinary temperature" as , with room temperature being . Merriam-Webster gives as a medical definition a range of as being suitable for human occupancy, and at which at which laboratory experiments are usually performed. People traditionally serve red wine at room temperature. This practice dates from before central heating, when room temperature in wine-drinking countries was considerably lower than it is today, usually in the range between and . The advice is therefore to serve the wine at, at most, about . Room temperature Colloquially, room temperature is the range of air temperatures that most
