To what temperature must a 350 ml gas sample at 26 C and 101 kPa be heated to increase its pressure to 175 kPa while in the same container.

I need to have this equation put into a formula with an answer, if you can please help me and put an explanation along with it, that would be great!!

I need that asap!! by today

look dear

as you know in your case you have the same volume as you said while the same container ..

the law is PV=nRT

it could be written as P1V1/T1=nR-----------1

this for the first condition (26 C and , 101 kPa)

for the new condition it is also the same rule P2V2/T2=nR---2

from one and two

P1V1/T1=P2V2/T2
and since v1=v2

so
P1/T1=P2/T2
now you can apply it very easy
hope that it work

This is a two part question.

First, you must find the "specific gas constant" (SGC). If you know the formula, you have enough information to answer this first question.

Using the SGC, you can now find the temperature you will need to heat the gas to to reach the desired pressure.

The answer I got is just a little over 245 C, but I don't know what your instructor wants you to round the decimal to. Warning!!! I did not double check my answer, so do your own math!!!

Try looking for an Ideal Gas Law calculator on the web, if you don't know the formulas.

look mom, i will confirm the tension, temperature or quantity of a theoretical gas if given a sequence variety of molecules and the cost of the different 2 variables. Whoooo-hoooo! or, if this is too sarcastic, possibly, in case you have an appropriate gas, I have been given the regulation that applies to it.

PV = nRT

But you don't know V.

You could either carry it through as an unknown, when it just cancels out, or you can use

P1V1/T1 = P2V2/T2

Which is always true for an ideal gas as long as n doesn't change.
