australopithecus · Answer

So you are completely lost? https://en.wikipedia.org/wiki/Ideal_gas_law read this

anonymous · Answer

yes , and ok .

australopithecus · Answer

Essentially what the ideal gas law is, is a way of modeling gases as particles that do not interact with each other, it is a simplistic way to look at gases. 

For this question you would use the original temperature pressure and volume to calculate moles of gas (n) then you would use the equation again to solve for Temperature using the moles volume and other pressure

australopithecus · Answer

This is usualy only really accurate for noble gases or hydrogen gas etc but even then it is still kind of inaccurate because real gases do interact with eachother

australopithecus · Answer

This has an effect on the properties of the gas of course but just thought I would tell you anyways.

anonymous · Answer

So the answer is Charles's Law.. Right ?

joannablackwelder · Answer

No,  Charles Law is for constant pressure. You have changing pressure and temp, with constant volume and number of moles.

My book calls P1/T1=P2/T2 Amontons' Law.
