Question

A container is divided into two equal compartments by a partition. One compartment is initially filled with He at a temperature THe; the other compartment is filled with oxygen (O2) at temperature T02. Both gases are at the same pressure. If we remove the partition and allow the gases to mix, what will be their final temperature

Answer 1

The final temperature of the mixture of helium and oxygen THe + O2.

Step-by-step explanation:

If we remove the compartments between helium and oxygen molecule, they will not react with each other because helium is a noble gas or stable gas due to complete its outermost shell so it cannot react with oxygen. So if they donot react with each other, no heat energy is absorbed or released and the temperature of the container remains constant. Both the molecules remain suspended in the air and donot react with each other.
