A valve 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 beca

use 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 =

Answer:

The temperature doesn't change

Explanation:

Given that:

$dU=dQ - dW$

Where

U: internal energy
W: work
Q: heat

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.
