Could Iron be evaporated. If Iron cannot be evaporated(base on my belief, Iron cannot be evaporated because it is a heavy element), then why Radon, an obviously heavier element to iron, is a gas?
All cold air intakes operate on the principle of increasing the amount of oxygen available for combustion with fuel. Because cooler air has a higher density (greater mass per unit volume), cold air intakes generally work by introducing cooler air from outside the hot engine bay. However, the term cold air intake is often used to describe other methods of increasing oxygen to an engine, which may even increase the temperature of the air coming into an engine. Some strategies used in designing cold-air intakes are: increasing the diameter of the air intake, allowing increased airflow. smoothing the interior of the intake to reduce air resistance. providing a more direct route to the air intake. tuning the length of the intake to provide maximum airflow at certain engine speeds (RPM). using a more efficient, less restricting air filter. Yes, it is true that it can suck up water if too close to the ground. As for how often to clean; Clean it every time you do your oil changes. 10 points please! Plus bonus points for the sucking up water question. ;D
Actually most of the substance on Earth is able to evaporate. It just depends on the temperature it need to evaporate
Yes, iron can be evaporated. Your assumptions are incorrect. The boiling point of iron is 2862 C. If you heat it up to that temperature, you get iron gas. Perhaps you're wondering why you have to get iron so hot to melt it or boil it, while radon is a gas AT ROOM TEMPERATURE. Melting points and boiling points are not simple. They don't go in order of the periodic table. Look at the low-numbered elements. Carbon (#6) is a solid. Nitrogen (#7) and Oxygen (#8) are gases. I don't know the details of what determines melting point and boiling point of an element. But it isn't simply light is a gas, and heavy is a solid at room temperature. It's much more complicated than that. Mercury (#80) is a liquid.
all substances can exist as solid, liquid, or vapor (gas) depending upon conditions. Solid iron can be melted or sublimated (converted directly to gas without melting), and liquid iron evaporated, if you provide the appropriate conditions. In reality, at any given P-T (pressure and temperature) conditions, all substances have an equilibrium vapor phase, which means that all substances will lose some molecules to the gas phase if there is space available for the gas phase, and thus all substances will evaporate completely if the system is open and the vapor phase is removed continuously. The only question is the matter of time; equilibrium vapor pressure can be extremely low so in practical terms, complete evaporation (probably sublimation in most situations with a solid) could take an absurdly long time. It is the presence of this vapor phase that makes it possible to detect solids by smell. You must have noticed that iron does actually have a particular odor of its own. Usually the odor of iron is detected secondarily, via change of the iron into a second substance with a higher vapor phase activity, but iron vapors are still present even in an unweathered or unaltered piece of iron. The concentrations in air are just usually very low.
