Question 3
4 / -1

The volumes of containers A and B, connected by a tube and a closed valve are V and 4 V, respectively. Both the containers A and B have the same ideal gas at pressures (temperatures) 5.0 ×10⁵ Pa(300 K) and 1.0 ×10⁵Pa (400 K), respectively. The valve is opened to allow the pressure to equalise, but the temperature of each container is kept constant at its initial value. Find the common pressure in the containers.

A
2.5 × 10⁵ Pa

B
2.0 × 10⁵ Pa

C
3.0 × 10⁵ Pa

D
1.5 × 10⁵ Pa

Solution

1 : 4

B
1 : 2

C
6 : 9

D
8 : 9

Solution
