Any substance dissolved in water or any substance that contains HYDROGEN is not required. I want to know if there's any substance that is liquid at room temperature and atmospheric pressure that doesn't contain HYDROGEN atom(s) in its make up.

Melting point: $-37^o C$, Boiling point $76^oC$ Perfluorodecalin.

Melting point: - 7.2 degree Celsius, boiling point: + 58.8 degree Celsius https://en.wikipedia.org/wiki/Bromine. Bromine. Yes.

Some elements become liquids at or near room temperature they include gallium, caesium and francium. I'm sure they're still other substances that are liquids at room temperature and atmospheric pressure. They do not contain hydrogen atoms. Carbon disulphide and bromine are both liquids at room temperature and atmospheric pressure.

Say "room temperature on an unseasonably warm day". One could make the argument that gallium is a liquid at room temperature, if you're willing to fudge a few degrees and go up to 30 C. asked 6 months ago viewed 111 times active 6 months ago.

Examples: Perfluorooctane:. You are not going to get a list of compounds which fit your description. However, many compounds of the form $\ce{C_nX_ }$, where X is a halogen for example, are liquids at room tempterature, and contain no hydrogens. It's a very general question.

Room temperature and pressure

Interior temperature humidity atmospheric pressure sensor with RS485 output T7418 for environmental monitoring.

Transmitters are designed for use in non-aggressive environment. Computerized design ensures temperature compensation of the humidity sensor and fail indication. State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Transmitter contains a microprocessor based control circuitry in a plastic case with connection terminals and sensors. Degrees Celsius and Fahrenheit are user selectable. Display is possible to switch off. Large dual line LCD for simultaneous display of T+RH or other humidity interpretation is an advantage.

For exacting interiors in building energy management and HVAC systems. Included in delivery:. Are designed for easy installation on ordinary KU68 wiring boxes for household switches and sockets.

dataloggers, thermometers, hygrometers.

Transmitter circuitry is galvanically isolated from power circuitry to prevent collision in RS485 network. Transmitters have the address space available from 1 to 255. Serial output RS485 - transmitter works with ModBus RTU communication protocol or with Advantech ADAM compatible protocol. Instrument works always in slave mode, i.e. Protocol is user selectable in special configuration mode by means of the PC. Communication speed is 110 to 115200Bd. Serial link enables to read actual readings and modify transmitter configuration. responds only to master device query. Measured values are converted to RS485 serial output.

Hydrogen becomes a solid at 25°C when subjected to a pressure of 57 kilobars. At 360 kilobars the calculated density of the high-pressure phase is 0.6 to 0.7 grams per cubic centimeter. The high-pressure phase appears as a transparent crystalline mass. The refractive index of the high-pressure phase increases sharply with pressure, indicating a density increase of similar magnitude.
