There are many, but here are just a few:
carbon dioxide, CO2
Some examples of substances that are solids at room temperature include grease. This becomes like a gelatin at room temperature. Butter is also an example.
Because the intermolecular forces of attraction are stronger in some substances than others at room temperature.
Carbon Dioxide, Ammonia and Methane are three examples of common compounds that are gases at room temperature.
There are many. Some examples would be carbon dioxide (CO2), carbon monoxide (CO), hydrogen (H2), oxygen (O2), all of the noble gases, nitrogen (N2), etc.
well go in a room and see if the substance is a solid, liquid or gas
Some are, but not all. Examples: 1 Carbon is a nonmetal and is solid at room temp., 2 Bromine, a nonmetal, is a liquid at room temperature, 3 Halogens and Noble Gases are nonmetals and exist as gases at room temp. all the non-metals, with the exception of bromine, are either in gaseous or solid state at room temperature. So, only about 50% of the non-metals are gases at room temperature.
There are many examples. At room temperature some examples might be nitrogen, hydrogen, helium, oxygen, neon, etc.
Yes. Both are gases at room temperature.
These substances are elements. Moreover they are elements which are solid at room temperature.
Gases at room temperature
The halogens that are gases at room temperature and pressure are fluorine and chlorine.
elements can combine to form new substances with different properties.
All of the noble gases (group 18) are gases at room temperature. In addition, fluorine, chlorine, oxygen, nitrogen, and hydrogen are gases at room temperature.
...because water molecules have strong intermolecular forces (hydrogen bonding) holding the moelcules together in the liquid state. Most other substances with similar molar mass do not exhibit hydrogen bonding, and thus they exist as gases.
They are gases at room temperature.
No, not all of them. But all gases at room temperature are nonmetals.
well ionic substances are solid at room temperature,they are generally soluble in water ,they have high melting and boiling points,while covalent substances are generally liquid and gases at room temperature,non-polar covalent substances are generally insoluble in water while polar covalent are generally soluble in water
Some nonmetals are solid at room temperature, and some are gases at room temperature, and bromine is liquid at room temperature.
70 oF = 21 oC This is a comfortable room temperature so many substances are gases at this temperature. Any substance that has a boiling point lower than 70 oF / 21 oC
Ionic compounds are solids at room temperature whereas molecular substances as a group are variable in their states of matter - some are solids, but many are liquids or gases.
Gases, hence noble "gases"
While the state of oganesson at room temperature is not known, there is no group in which all elements are gases.
