Avalve to a new chamber in the bottle is opened, and the gas expands to 2 x 10-3 m3. (the gas does no work in this process because the gas molecules don't have anything moving to push on.) after a while, the parts of the gas re-equilibrate, without exchanging heat with the outside. what is the new temperature, t? t =

The temperature doesn't change

Explanation:

Given that:

Where

If the gas does no work and doesn't exchange heat with the outside there insn't a variation of the internal energy.

Internal energy is realted to the energy in the molecules, they vibration and theregore the temperature.

So, if there isn't a change in the internal energy you may say that there isn't a change in the temperature.

The increase in the volume is balanced by a decrease of the pression.

A mixture can vary in composition, but a pure substance cannot. think of salad dressing in a bottle and then think of pure water.
