Question

wo insulated cylinders A and B with volumes

V_A = 2.0 m³

and

V_B = 6.8 m³

contain chlorine gas at different pressures and temperatures. The cylinders are insulated (no heat is lost to or gained from the outside) and connected by a valve. Initially, the valve is closed and the gas in the two cylinders has the following values:

P_A = 4.0  10⁵ N/m²,

T_A = 220 K,

P_B = 2.5  10⁵ N/m²,

T_B = 580 K.

The valve is opened to allow the contents in the two cylinders to mix until the pressure equalizes.

(a) Assuming there is no change in the temperatures of the containers themselves, determine the final temperature of the gas in the two cylinders. The atomic mass of chlorine gas is 35.4527 u.
K

(b) Determine the final pressure.
N/m²
