500mL of air are trapped in a tube over mercury at 25°C. It is found that, after six days, the air has expanded so that 32mL have escaped the tube. What total

temperature change occurred over this period if the pressure remained constant?

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:

Replacing:

Solving:

T2= 19.072 K

The new temperature is 19.072 K.
