# A gas initially exerts a pressure of 82 atm at 17 celsius. What should be the temperature to increase its volune by 30%?

What formula should I use?

How do you solve it?

Relevance
• 17C = 290.15K; the temperature would have to be raised by 30%, so up to 377.2K, or 104C.

• for all these 2 state gas law type problems do this

.. (2) rearrange for your unknown variable

.. (3) identify and cancel anything held constant

.. (4) plug in the data, chug out the results... T must be absolute

**********

this problem

.. P1V1 / (n1T1) = P2V2 / (n2T2)

rearranging

.. T2 = T1 * (n1 / n2) * (P2 / P1) * (V2 / V1)

we assume moles is constant, we assume P is constant

.. T2 = T1 * (V2 / V1)

solving... .. note that V2 = 1.3 * V1

.. T2 = (17+273 K) * (1.3 V1 / V1)

.. T2 = (290K) * 1.3 = ___ K = __ °C

you get to finish

Assuming pressure is constant, 30% more volume is 30% more temperature.

New temperature = (17C + 273) * 1.3
