Is heating a wood splinter a chemical change and why?
Heating the wood (and not burning it) would be a physical change. If the wood splinter catches fire and burns, then it is a chemical change because a combustion reaction has taken place and the wood is no longer the same chemical composition. It will turn into carbon dioxide and water, and other materials left over.
Which part of the graph would indicate a phase change is place?
a steep upward sloping line
Did a chemical reaction take place when sulferpowder and iron filling were mixed without heating explain your answer?
No, the sulfur and iron still have their individual properties. Iron is still magnetic and the sulfur can be dissolved by carbon disulfide leaving behind the iron.
Is heating of iron wire physical or chemical change?
Since the chemical structure of the iron (Fe) does not change, it is a physical change. I would like to point out that this does make the likelihood that a chemical change will take place higher, more energy equals a faster phase transformation. If the iron it is sitting in air, the outer surface is likely under going a chemical change into iron oxide (FeO, Fe3O4, and Fe2O3) more commonly known as rust. Hence, iron as with most metals is found as Iron oxide and processed into Iron. More facts about iron can be found here: http://en.wikipedia.org/wiki/Iron
How is natural gas transported to users without any pipeline?
When natural gas is cooled to very low temperature it turns into a liquid is called liquified petroleum gas or LPG. It can be moved from place to place in special cylinders. In mountainous areas where there are no gas pipelines, many people use LPG for heating and cooking.
Can evaporation takes place without heating?
no

How does rate of diffusion of a gas in a liquid change on heating?
if the temp is higher then diffusion take place faster
Inertia in a sentence?
Inertia is, essentially, the body's resistance to change. An example sentence would be: Without inertia, we would be all over the place.
Where can one find reviews on air heating?
The best place to find reviews on air heating would be on a site such as Yelp. Many businesses who work in the air heating area are reviewed by users.
What causes weather to?
The wind is blowing rain and fronts all over the place. Without wind,the weather would never change
Is heating sand to its melting point a chemical or physical change?
Heating is purely physical, though at higher temperatures also some or many chemical reactions might take place: e.g. decomposition (break down) of mineral carbonates into oxides and carbon dioxide.
What causes a chemical change?
No, not always. For example, if you mix salt and water, no chemical change takes place. The salt dissolves in the water and a solution is formed, which is not a chemical change because the salt and water retain their individual chemical compositions.
Why is my car over heating?
it can be many stuff but in your place i would check first the coolant level and the thermostat
In order to heat a room evenly should heating vents be placed near the floor or near the ceiling of the room?
It would be better to place the heating vent near the floor because the heat will travel up and down, so that way the room would be heated evenly. If you place it near the ceiling, the heat would not heat the floor that well, since the heating vent sucks back in the heat
How would life be different without soldiers?
Life would change nO freedom or government safety no special treatment it would all be different Answer By the way, there has never been a time or place in human history when there were no soldiers or warriors. We would all have to change dramatically to make this happen.
