Liquid Argon Liquid nitrogen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F. (–90°C). Liquid nitrogen has a boiling point of –320°F (–196°C). The temperature difference between the product and. the surrounding environment, even in winter, is substantial.

Solids, Liquids and Gases We are familiar with the three states in which water exists--as ice up to its melting point of 0 °C, as a liquid between 0 and 100 °C, and as a gas (steam) above 100 °C. We also know that any substance can be vaporized if the temperature is high enough.

About Temperature Between 3.0K and the triple point of neon (24.5561K) the temperature is defined by means of a helium gas thermometer. Between the triple point of hydrogen (13.8033K) and the freezing point of silver (961.78°K) the temperature is defined by means of platinum resistance thermometers.

- Known as a liquid but obviously it can be all three. Mercury is a liquid at room temperature, it will solidify if you make cold enough, -40 C and be gas if you make it hot eno…ugh, +357 C. It expands and contracts easily in this liquid form, which is why old thermometers used it.

Liquid Helium When helium is cooled to a critical temperature of 2.17 K (called its lambda point), a remarkable discontinuity in heat capacity occurs, the liquid density drops, and a fraction of the liquid becomes a zero viscosity superfluid.

Metallic hydrogen Helium-4 is a liquid at normal pressure near absolute zero, a consequence of its high zero-point energy (ZPE). The ZPE of protons in a dense state is also high, and a decline in the ordering energy (relative to the ZPE) is expected at high pressures.

Atoms and elements Hydrogen occurs as a gas that you can’t see and can’t smell. It is about 14 times lighter than air. When you combine two atoms of hydrogen with one atom of oxygen you get a water molecule H 2O. Like nitrogen, hydrogen can also be condensed to a liquid that freezes at – 259°C (-434°F) and boils at -252°C (-423°F). Hydrogen is one of the most common elements in our universe. The sun and many stars are made of hydrogen.

- Mercury and water are both liquid at room temperature and 1 atmosphere of pressure. You can make water boil, however, by putting it in a vacuum! Boiling is the process of a substance changing from liquid to gas phase.or Hydrogen, the boiling point is -253 degrees Celsius; for Mercury it is 357 degrees Celsius, and for Iron it is 2,750 degrees Celsius. From these numbers you can see that at room temperature (and indeed for nearly any temperature found on Earth) Hydrogen is a gas, Mercury is a liquid, and Iron is a solid.

- Cesium, for example, becomes liquid at 82° (28°C). It's also believed that francium would be liquid at or just above room temperature, but this highly-unstable radioactive element has yet to be manufactured in a quantity which would confirm this.

- As the temperature is increased they will melt and become liquids. Each element melts at a different temperature, called it's melting point. Hydrogen melts at -259 degrees Celsius. Mercury melts at -39 degrees Celsius. Iron melts at 1,535 degrees Celsius. As the temperature is increased still further, each element will boil and become a gas. Each element boils at a different temperature, called the boiling point.

What Makes a Good Dog a Good Kids' Dog? Of course, some cautions apply. A dog can be the perfect child’s companion — but it depends on the dog and how you teach both dog and child to interact. So what makes a dog a good kids' dog? First, of course, it needs to not bite kids, even when the kids are provoking the dog.

Liquid Elements - Elements That Are Liquids Near Room Temperature There are two elements that are liquid at the temperature technically designated 'room temperature' or 298 K (25° C) and a total of six elements that can be liquids at actual room temperatures and pressures. Elements That Are Liquid at 25°C. Room temperature is a loosely defined term that can mean anywhere from 20°C to 29°C. For science, it's usually considered to be either 20°C or 25°C. At this temperature and ordinary pressure, only two elements are liquids.

- What is neon's state of matter? Full Answer Hydrogen's state of matter can change when the temperature changes, becoming a liquid at temperatures between minus 423.18 and minus 434.49 degrees Fahrenheit. It becomes a solid at temperatures below minus 434.49 F. Due to its high flammability, hydrogen gas is commonly used in combustion reactions, such as in rocket and automobile fuels.

An Introduction To Extreme Cooling Liquid helium, or LHe, has only recently started being used for CPU cooling, due to its high cost and extremely cold temperature. With a boiling point of around -269°C, it is the closest thing we have to bringing our components to absolute zero.

- Hydrogen lines will be strong for temperatures = 4,000 to 12,000 K. Helium atoms hang onto their electrons more strongly and, therefore, require higher temperatures of 15,000 to 30,000 K to produce absorption lines in the visible band.
