Formula of work done, W = - P (final volume - initial volume)
Here, W = work done
P = external pressure
External pressure is constant. In case of expansion final volume is greater than initial volume, therefore change in volume is positive.
W = negative ( positive )
W = negative
So, In case of expansion, the negative value of work indicates that the work is done by the system on the surrounding. Energy is released by system.
The sum of the forces of all of the molecules placing the wall divided by using the area of the wall is described to be the pressure. The pressure of a gasoline is then a measure of the common linear momentum of the moving molecules of a gas. The unit of pressure is pascal.

Answer:
The new temperature is 19.072 K.
Explanation:
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure. This law says that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules.
In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
Assuming that a certain volume of gas V1 that is at a temperature T1 at the beginning of the experiment varies up to a volume of gas V2, then the temperature will change to T2, and it will be true:
In this case:
- V1= 500 mL
- T1= 25 C= 298 K
- V2= 32 mL
- T2= ?
Replacing:
Solving:
T2= 19.072 K
<u><em>The new temperature is 19.072 K.</em></u>
