Задача 20507.

There are two thermally insulated vessels of equal volume, filled with the same gas. The gases in the vessels are given the same amount of heat. The initial temperatures of the gases are equal. The initial gas pressure in the second vessel is 2 times greater than in the first. The final gas temperature in the first vessel is T1=400 K, in the second T2=300 K. Find the initial temperature of the gases.
