Mostly true, though methylamine and ethylamine are both gases at room temperature.
The dividing line between liquids and solids at room temperature of 1-aminoalkanes is about 1-aminododecane, which melts at 27-29 degrees Celsius.
Nonmetals can be solid, liquid and gas at room temperature.
There is no set temperature for solids. Each element is different. At room temperature we have solids, liquids and gases. Therefore the temperature for a solid is different for each element.
Solids become liquids when the temperature reaches melting point, groups of particles start to brake away from each other. This is when the solid starts becoming a liquid. Liquids become solids on cooling, the particles move slower and become a solid.
Depending on the temperature, different things could either be a gas, solid, or liquid. For example, water is a solid at 32 degrees Fahrenheit and when it is warmer than that it is a liquid.
elemental sulfur (yellow solid)
Solid
when it is cold temperature it forms a solid
No. Many compounds are liquids (water, hexane) and gasses (carbon dioxide, ammonia) at room temperature. Many compounds are solid at room temperature and can, but often do not exist in the form of a powder.
Solid
Covalent.Every compound can exist as a solid, liquid, or gas, given the right temperature and pressure. This is also true of every element, with the single exception of helium, which has no solid phase, no matter how cold it is. Helium is unique.
At stp (standard temperature and pressure) silver is a solid. The only elements that are liquids at stp are bromine and mercury. There are more elements that are gases than liquids.
All solid can be liquified if the temperature is high enough.
Temperature causes the matter to exist in three different states. They are Solid, Liqid and Gas. If temperature is increased matter changes into gas and if temperature is decreased it changes into solid.
Silver would be a solid at room temperature. This is also what happens with gold. If both were heated, then they would be liquids.
Such liquids have high density, good electrical conductivity and become solid as temperature decreases from their melting point.
Carbon at room temperature is solid.
Para toluidine appears as white lustrous plates or leaflets with an amine odour at room temperature. It melts at 430C.
