Math Question regarding pressure and temperature?

Question

Yes, this is homework, but I'm so confused! Can anyone help?!

--

If gas is initially at room temp (20 C) and is heated in an isobraic (constant pressure) process, what will be the temp. of the gas in degress celsius when it has expanded to a volume of 0.600 m^3?

Answer 1

You need to know this basic law: {[preasure]*[volume]}/[temperature]={[new preasure]*[ new volume]}/[new temperature]

Your problem doesnt involve preasure so take that part out:
{[volume]}/[temperature]={[ new volume]}/[new temperature]

Shorten that to V1/T1=V2/T2

Now substitute you information in. 1/20=.600/X
(1 because you start at room temperature)
Then solve for X



At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in kelvins) increases or decreases
