See Gallium in its Liquid and Solid FormsSymbol: GaAtomic number: 31Melting point: 85.58°F (29.76°C)Parent material class: Meta Why is gallium liquid in room temperature? Gallium melts at room temperature and has one of the largest liquid ranges of any metal. The melting point of gallium is used as a temperature reference point. At room temperature, gallium metal is unreactive towards air and water due to formation of a passive protective oxide layer Gallium Metal, the metal which melts at room temperature!https://en.wikipedia.org/wiki/Gallium
Gallium Metal Liquid: Nanoparticles (NPs), and noble metal NPs, are versatile agents with a variety of applications. The unique characteristics of noble metal NPs, such as high surface-to-volume ratio, broad optical properties, ease of synthesis, and facile surface chemistry and functionalization hold pledge in various fields. Gallium is a metal that literally melts in your hand. It has low toxicity, near-zero vapor pressure, and a viscosity similar to water. Despite possessing a surface tension larger than any other liquid (near room temperature), gallium can form nonspherical shapes due to the thin, solid native oxide skin that forms rapidly in oxygen .

The liquid metal clings to (wets) glass and similar surfaces. The crystal structure of gallium is orthorhombic With a melting point of approximately 30°C, gallium is a liquid at just above room temperature. When alloyed with other elements (notably indium), the resulting melting point is below room temperature. This low melting point has made the gallium alloy family a non-toxic replacement for mercury in certain applications that require a liquid metal at.
GaInSn or galinstan is a eutectic alloy composed of 68%wt gallium, 22%wt of indium, and 10%wt of tin.

The resistivity of EGAIn is ~29.4X10-6 W-cm.The low viscosity liquid is easily moldable and useful for various electronic applications Yup, the melting point of gallium is just 85.6 degrees F (29.8 degrees C), which means that it melts into a mirror-like puddle in your hot little hand. In its liquid form, gallium looks a lot like mercury, but gallium isn't toxic like mercury so it's safer to handle (although it can stain your skin) It is one of four metals mercury, cesium, and rubidium which can be liquid near room temperature and, thus, can be used in high-temperature thermometers. It has one of the longest liquid ranges of any metal and has a low vapor pressure even at high temperatures. There is a strong tendency for gallium to supercool below its freezing point The liquid nature of gallium enables fabrication methods—such as microfluidics and sonication—that are not possible with solid materials. Gallium-based liquid metal particles possess several notable attributes, including a metal-metal oxide (liquid-solid) core-shell structure as well as the ability to self-heal, merge, and change shape In a broad sense, each metal can be known as the liquid metal when it exists in a liquid form. In this review, we focus on metals that are liquid at room temperature. Taking gallium (Ga) as an example, the existence of Ga dimer gives the metal certain covalent properties and decreases the melting point

The surface of liquid metals plays a critical role in establishing thermodynamic equilibria (both mass and energy) at the interface between liquid metal and air. The unique thermodynamic environment triggers a new field of the liquid metal surface chemistry system. These surface characteristics lay the foundation of understanding liquid metals and extending their applications Gallium's boiling point, 2673 K, is more than eight times higher than its melting point on the absolute scale, making it the greatest ratio between melting point and boiling point of any element. Unlike mercury, liquid gallium metal wets glass and skin, making it mechanically more difficult to handle (even though it is substantially less toxic and requires far fewer precautions)

Wetting state transition regulated by surface roughness has increasing importance for its wide applications. Molecular dynamics simulations have been performed to study the wetting state transition induced by surface roughness in the gallium-carbon system. There is a transition from the Wenzel state to the C PCCP Emerging Investigator Liquid metal (read Gallium) will seep into the copper heatsink. How long this will take depends on the product, and usage mainly. As mentioned in the beginning - all LM thermal pastes will have Gallium as their main ingredient. The good news is copper will not be destroyed and become brittle like aluminum Gallium−/indium-based liquid metal, a kind of newly emerging functional metal material with fluid state at room temperature, implements many complex functionalities such as special wettability. . Gallium melts just above room temperature, like butter, so you can't hold it in your hand for too long. It's fairly dense, though not anywhere near as dense as mercury, and would be easier to row a boat on

We demonstrate a magnetocaloric ferrofluid based on a gadolinium saturated liquid metal matrix, using a gallium-based liquid metal alloy as the solvent and suspension medium. The material is liquid at room temperature, while exhibiting spontaneous magnetization and a large magnetocaloric effect. The Review Surface Chemistry of Gallium-Based Liquid Metals Yiran Ding,1 ,3Mengqi Zeng,2 and Lei Fu1 ,2 * SUMMARY The surface of liquid metals plays a critical role in establishing ther-modynamic equilibria (both mass and energy) at the interface be-tween liquid metal and air Gallium easily melts on our hand because its melting temperature is well below our body temperature. Mercury is already a liquid at room temperature. Nevertheless, the key difference between gallium and mercury is that gallium has a very low density compared to mercury. The below info-graphic tabulates the differences between gallium and mercury Gallium metal is silvery white minor metal with low melting point and high boiling point, which is liquid when temperature above 29℃, but solid when temperature under it. It is also soft even when solid.Ga is avaliable in liquid, solid, granule. Liquid gallium tends to undercool that mean it would't solidify even temperature under 0℃ In the present study, models for liquid gallium corrosion with austenitic stainless steel are studied and discussed. This paper presents a mathematical analysis of liquid gallium corrosion, especially the surface recession due to solubility and diffusion, in a static cell, as well as the mass exchange at the liquid/solid interface

Gallium, you see, melts at 30 o C, which means that on a hot day, you hold it in your pocket at your peril. Surprisingly however it's not very volatile. In fact Gallium has the largest liquid range of any material known to man. Its boiling point is just over 2400 o C. So unlike other liquid metals, there is no toxic vapour to worry about Eutectic gallium-indium is an electrically conductive liquid metal at room temperature used in microfluidic devices to make microscale electronics and electromagnets. Interestingly, for small surface stresses, the fluid behaves as an elastic solid, but readily flows once enough stress is applied to the surface Gallium is a metal which, due to its melting point of 29.76°C, will turn to liquid in your hand. And, unlike mercury, pure gallium is safe to handle. Bringing gallium and aluminium together has some interesting and occasionally rather explosive results, as we discovered in this video
Liquid metals exhibit remarkable mechanical properties, in particular large surface tension and low viscosity. However, these properties are greatly affected by oxidation when exposed to air.
