Two identical containers are adjacent to each other. They both have Volume =3.5 L and Pressure = 1atm. One contains O2, a diatomic gas, (molar mass 32g/mol) at initial temperature 250K. The other contains argon, a monoatomic gas, (molar mass 40g/mol) at some unknown initial temperature T. After the boxes exchange heat (but not particles) they both reach a final temperature of 400K. If you assume they both behave as perfectly ideal gases, what is the initial temperature of the Argon gas.
Two particles each have a mass of 6.1 x 10-2 kg. One has a charge of +4.1 x 10-6 C, and the other has a charge of -4.1 x 10-6 C. They are initially held at rest at a distance of 1.0 m apart. Both are then released and accelerate toward each other. Ho..
