The pressure inside two gas cylinders of volume 25 m 3 and 50 m 3 are 10 kPa and 20 kPa respectively. The cylinders are kept at the same temperature and separated by a valve. What is the pressure in the combined system when the vale is opened?
Text Solution
Verified by ExpertsThe correct answer is:
C
n T = n 1 + n 2
P × 75 = 250 + 1000 = 1250
P = 16.7 kPa
