Question

A gas at 65 degrees Celsius occupies 4.22L. At what Celsius temperature will the volume 3.87L, assuming the same pressure?

-kay so ive tried this one like a million times & i cant seem to get the right answer so pls talk me through the steps. like i know the equation is V1/T1=V2/T2 (volume & temp) & all it is is plugging in #s but im not getting the right answer !!! HELP. Like i even converted celsius to Kelvin and that's not workin. cos i have an answer sheet but doesnt shw us how.

Answer 1

If you had shown your work we could find your error. And you MUST convert temperature of 65 C to Kelvin (273+65 = 338 K), solve for the new T, then subtract 273 from the final T to arrive at final C. I suspect you may not be converting the final K temperature back to C.

so this is what igot
338k x 4.22L/3.87L=368-273
then i get 95 degress celsius.
& the book answer says 37 degres celsius. ): what am i doing wrong !
