Iron is a metal, and metals are solid at room temperature.
True. Saturated fats have a higher melting point and tend to be solid at room temperature, while unsaturated fats have a lower melting point and are typically liquid oils at room temperature.
True A+
Oxygen. Oxygen is a gas making it react faster, while sulfur is a solid.
Some do while others do not. To be solid a substance must merely have a melting point that is above room temperature. Gallium has a melting point just above room temperature, so it is normally solid but it will melt in the palm of your hand. By contrast Tungsten has such a high melting point that not even the hottest lava from Earth's volcanoes can come close to melting it.
True A+
Carbon can mix with oxygen as fine particles in suspension, which will eventually settle out if the mixture remains undisturbed. Since oxygen is a gas at room temperature while carbon is a solid, it is difficult to thoroughly mix them.
Copper Sulphate is a powder at room temperature, therefore it is a solid.
Hydrogen and oxygen are both gases at room temperature, while water is a liquid at room temperature.
No, while it is possible to melt manganese it is a solid at room temperature
the solubility of a solid increases with temperature while those of gasesdecrease with rise in temperature.
It depends at what temperature. If we talk about room temperature then a natural state of a metal like Mercury is liquid (same as some non-metals like glass) while others like Copper are solid. Of course, in the vacuum of space where there is no influence of heat or sunlight, all metals are solid.
it is described as vapourization
During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat energy which we supply is absorbed by them for this purpose. So change in temperature is not observed.
Yes, nitrogen is found as N2 and is a gas at room temperature whilst phosphorus is found as P4 and is a solid at room temperature.
True. Saturated fats have a higher melting point and tend to be solid at room temperature, while unsaturated fats have a lower melting point and are typically liquid oils at room temperature.
You heat s solid, pure piece of it slowly and measure the temperature of the melt while there is still solid present.
