What state is water at 20 degrees Celsius?
liquid
Water, at a standard room temperature of 20 degrees Celsius, is a liquid.
What is the state of mercury at 25oc?
Liquid Elements at 25°C Mercury is the only metal that is a liquid at room temperature. It is a shiny, silver metal with a melting point of 234.3210 K (−38.8290 °C, −37.8922 °F) and boiling point of 629.88 K (356.73 °C, 674.11 °F). The reason mercury is a liquid is due to relativistic effects.
What is the density of mercury at 20 degrees Celsius?
| Temperature – T – (oC) | Density – ρ – (kg/m3) | Specific Heat – cp – (103 J/kg K) |
|---|---|---|
| 20 | 13545 | 0.139 |
| 50 | 13472 | 0.139 |
| 100 | 13351 | 0.137 |
| 150 | 13231 | 0.137 |
Is mercury a solid liquid or gas?
Elemental (Metallic) Mercury Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature.
What is in dry ice?
Dry ice has just one ingredient: carbon dioxide. Technicians create dry ice by pumping liquid carbon dioxide into holding tanks, which reduces the temperature to -109° F and pressurizes the substance into solid blocks or pellets.
What state of matter is carbon dioxide at 20 degrees Celsius?
gas
Explanation: Carbon dioxide is a gas at room temperature. The sublimation point of carbon dioxide (dry ice) is −78.5∘C .
What is the symbol of mercury?
Hg
Mercury/Symbol

What is the density of water at 20 degrees Celsius?
0.9982 g/mL
UKAS ISO/IEC17025 and ISO Guide 34 certified, density: 0.9982 g/mL at 20 °C, density: 0.9970 g/mL at 25 °C.
What is the freezing point of mercury?
-38.83 °C
Mercury/Melting point
Is it illegal to have a mercury thermometer?
Those days have passed. Since 2001, 20 states have banned mercury “fever thermometers” for medical use, and regulations tighten every year. But as of today the federal government has more or less killed the mercury thermometer in the United States—NIST has announced it will no longer calibrate mercury thermometers.
Can you touch mercury?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
What’s the temperature at which mercury can be frozen?
Mercury Physical properties. Mercury can be frozen changed into a solid at a temperature of –38.85°C. It can be changed into a gas when boiled at 365.6°C.
Mercury – Melting Point. Melting point of Mercury is -38.9°C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at
What is the density of mercury per cubic centimetre?
The density of mercury is 13.59 grams per cubic centimetre. It has two physical properties of special interest. Very high surface tension. Very good conductor of electricity. Surface tension is a property of liquids that makes them act like they are covered with skin.
What are the physical properties of liquid mercury?
Mercury Physical properties 1 Very high surface tension. 2 Very good conductor of electricity. More
