A change in temperature, pressure, or volume (all three are related via gas laws)
Example:
Cooling a hot substance may result in the condensation of its gaseous state into a liquid state. It may also cause the solidification of a liquid into a solid form as the substance loses its heat energy and transitions to a lower temperature state.
Gaseous iron is highly reactive and can easily react with the glass container, causing it to break or degrade. Additionally, the high temperatures required to keep iron in a gaseous state would likely cause the glass to shatter.
The possessive form for the noun substance is substance's.Example: The substance's origin could not be determined.
Some synonyms for pure substance could be chemical compound, element, or homogenous material.
If it is wet, it will get the chemical wet, which will add to its mass, and could cause an undesired reaction. If it is dirty, the substance on the spatula would affect the purity of the chemical, and could cause an unwanted reaction, or could also affect the mass.
Condensation
Cooling a hot substance may result in the condensation of its gaseous state into a liquid state. It may also cause the solidification of a liquid into a solid form as the substance loses its heat energy and transitions to a lower temperature state.
jaja yes
Yes, the thermal expansion is very important in physics and technology.
No.
CO2(aq) because a solution means the substance is dissolved in water.
The substance may contain a smaller substance that could invade your lung system and irritate the sells in your lungs causing your eyes to itch or causes you to cough.
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
A mixture of gaseous elements and compounds could contain various gases like oxygen, nitrogen, carbon dioxide, and water vapor. The gases can exist together without chemically combining to form a new substance. This mixture might be found in the Earth's atmosphere or industrial processes.
You need to see a doctor as soon as you can. There are a number of conditions that can cause these symptoms, but because one of them is cancer you should not delay.
no it could not
The magnet by itself would not kill you. However... If the magnet was sharp or pointy it could cut or perforate your digestive tract, which could kill you. If the magnet was too large to pass through your digestive tract it could cause a fatal obsruction. If the magnet was coated with a toxic substance, that substance could kill you.
