Which substance is liquid at C?
Benzene melts at 6°C and boils at 80°C; it is a liquid at room temperature.
If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid.
Sodium chloride melts at 801°C and boils at 1413°C.
Sodium chloride is a solid under normal conditions..
What liquids can boil?
Boiling is the method of cooking food in boiling water or other water-based liquids such as stock or milk. Simmering is gentle boiling, while in poaching the cooking liquid moves but scarcely bubbles.
What boils faster than water?
The Claim: Cold Water Boils More Quickly Than Hot Water. The claim is repeated so often that many people accept it as fact. But according to scientists, the notion that a body of cold water will reach boiling temperature more quickly than an identical body of hot water under the same parameters is simply false.
Is boiling liquid to gas?
Boiling is a phase transition from the liquid phase to the gas phase that occurs at or above the boiling temperature. Boiling is the rapid vaporization of a liquid and occurs when a liquid is heated to its boiling point.
What liquid has highest boiling point?

What bacteria survives boiling?
Boiling does not ensure the elimination of all micro-organisms; the bacterial spores Clostridium can survive at 100 °C (212 °F) but are not water-borne or intestine affecting.
What is liquid explain?
A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. … When a liquid is cooled, the atoms or molecules lose kinetic energy. If the temperature becomes low enough, the liquid becomes a solid.
What increases boiling point?
The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. The influence of each of these attractive forces will depend on the functional groups present. Boiling points increase as the number of carbons is increased.
What is a substance that does not contain water?
Oil is a common substance that, when pure, contains no water whatsoever. In fact, oil famously won’t even mix with water. Substances like metal, carbon, and even oxygen can also be liquid, but they tend to be liquid at temperatures and pressures we don’t experience in day to day life.
What state of matter is oxygen at 25 degrees Celsius?
Since room temperature is taken at 298K (25 °C, 77°F), and is greater than oxygen’s boiling point, it exists as a gas at room temperature.
What liquid boils at 78 degrees Celsius?

Which substance is liquid at room temperature?
Only two elements are liquid at standard conditions for temperature and pressure: mercury and bromine. Four more elements have melting points slightly above room temperature: francium, caesium, gallium and rubidium.
How do you know if a substance is liquid at room temperature?
If the boiling point (b.p.) is below room temperature, it’s a gas. If the b.p. is above room temperature, and the m.p. is below room temperature, it’s a liquid. If the m.p. is above room temperature, it’s a solid.
What is the boiling point of liquid?
The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).
Which substance is liquid at 30 degrees Celsius?
At this temperature and ordinary pressure, only two elements are liquids: Bromine. Mercury.
