# Math Help - Do I use this?

1. ## Do I use this?

5.99 cubic meter of gas initially at 1 atm. pressure and 273K is placed under pressure of 4 atm. pressure.. The final temp is measured at 25 deg C. What is the final volume.

Do I convert the 273K to celcius, which worked out to 0 deg cel?? is that correct?

Do I use the liquid volume expansion in this equation??
I am not to sure, thanks.

2. use the combined gas law:

$\dfrac{P_1\;V_1}{T_1} = \dfrac{P_2\;V_2}{T_2}$

Use temperature in terms of Kelvin... Conversion to celsius is not necessary here..

3. Thank you, got the answer of 1.36 cubic metres.

4. Did you mean 1.63? Thats my answer.
