Question

A sample of gas has a pressure of 700 mmHg and 300 Kelvin. At what temperature would the pressure be if the pressure is lowered to 600 mmHg? *

Answer 1

Answer:

Given,

Pressure (P1) = 700 mm of Hg

Temperature (T1) = 300 K

Pressure (P2) = 600 mm of Hg

According to Regnault's Pressure Law,

P1/T1 = P2/T2

700/300 = 600/T2

700T2/300 = 600

T2 = 600*300/700

The Temperature would be 257.142 K or, -15.857°C.

I hope this helps.
