AI Thread Summary
To verify the gas constant R using a lighter, the relevant equation is PV=nRT, but measuring the pressure inside the lighter is unnecessary. The gas inside is in liquid form, which means it does not follow the ideal gas law. Instead, using the combined gas law may be more appropriate for the experiment. One participant found an alternative method to proceed with the experiment successfully. Therefore, focusing on the gas's state is crucial for accurate results.

Homework Statement


I need to do an experiment to verify the gas constant R and I can only use a lighter. The equation useful is PV=nRT but I don't know how I can find the pressure inside the lighter. Any help is appreciated! :D

Homework Equations



I don't know what other equation might be used other than PV=nRT

You may be able to use combined gas law to solve this. Does you experimental design allow for the construction of a manometer?
 
There is no need to measure the pressure inside the lighter. Besides, it won't help, as the gas inside is in a liquid form, so it doesn't obey the ideal gas law.

Yeah that's right, but I found a way to do it so it's all good now :)

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
