The simplest way to put it would be to say borders move more than mountains.
A world map is going to be physically unchanged for hundreds of thousands of years, a political map is likely to have inaccuracies after a decade or two.
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical 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
A physical map shows the elevation. A political map shows more detail about the place than a Physical map does.
The bubbles themselves are physical. What caused them might have been a physical change or a chemical change; it's impossible to say without more information.
A mixture is a combination of two or more subtances.Subtances in a mixture can be separated.This means that they are chemically combined.I would prefer physical change cause mixtures are made by physically combining two or more subtances.The solids,liquids,or gases in a mixture are not chemically combined.They can be easily seperated.
a political map
The political map as continents and territories over time change, divide and or come together. The physical map does change but this is eventually after hundreds or thousands of years.
A political world map is more likely to change than a physical world map because political boundaries, governments, and international relations are constantly shifting compared to physical features like landforms and climate which change at a slower pace.
A political map is most likely to change because if you think of politics the politics can change anytime but people can't just say there's a new continent by tomorrow.
Some other types of maps include thematic maps which focus on specific themes such as population distribution or climate patterns, topographic maps that show elevation and terrain features, and cartogram maps that distort the size of regions based on a specific variable like population or economic data.
"Better" is not the term you would use for comparing physical to chemical without defining the principle of what is better, but a chemical change is a more permanent change that will more than likely require input of energy.
Physical Change
no. its chemical properties do not change, only its apperance.
It wouldn’t change much. Might split the vote allowing one party to win over the other.
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.
It is a physical change because is it changing the leaf? No, no it isn't so it is a physical change.
The size is not a change. If there is a change in size that could be a physical change, but that depends on why its sized increased. If the sized increased because more material was added or because it was heated, those are examples of a physical change that caused a change in size. If the sized increased because it reacted with some other chemical, making it take up more space, that would be a chemical change that caused the size to change.
