Joe Johnston · Answer 1

750mmHg

Explanation:

The following data were obtained from the question:

T1 = 127°C = 127 + 273 = 400K

T2 = 27°C = 27 + 273 = 300K

P1 = 1000mmHg

P2 = ?

P1/T1 = P2/T2

1000/400 = P2 / 300

Cross multiply

400 x P2 = 1000 x 300

Divide both side by 400

P2 = (1000 x 300) / 400

P2 = 750mmHg

Therefore, the new pressure after cooling is 750mmHg
