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?

Respuesta :

Answer:

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
