Two Containers Contain the Same Gas at Different Temperatures and Pressures

Two containers contain the same gas at different temperatures and pressures as detailed in the drawing below.The small container has a volume of 1 liter and the large container has a volume of 2 liters.The two containers are then connected to each other using a thin tube and the system is allowed to reach equal pressure and temperature in both containers.If the final pressure is 200 kPa,what is the final temperature? You may assume that the connecting tube has negligible volume and mass.

A) 400 K
B) 500 K
C) 550 K
D) 300 K
