A gas has a pressure of 645 Torr at 128 ºC. What is the temperature (ºC) of the pressure increases to 824 Torr at constant volume and moles?

512 K

Explanation:

Initial pressure P1 = 645 Torr

Initial Temperature T1 = 128 ºC + 273 = 401 K (Upon converting to kelvin temperature)

Final Pressure P2 = 824 Torr

Final Temperature T2 = ?

The relationship between the variables is given as;

P1 / T1  = P2 / T2

Making T2 subject if formula we have;

T2 = P2T1 / P1

Inserting the values we have;

T2 = 824 * 401 / 645 = 512 K

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
