Hello!

The answer is:

When the pressure that a gas exerts on a sealed container changes from

22.5 psi to 19.86 psi, the temperature changes from 110°C to

65.9°C.

Why?

To calculate which is the last pressure, we need to use Gay-Lussac's law.

The Gay-Lussac's Law states that when the volume is kept constant, the temperature (absolute temperature) and the pressure are proportional.

The Gay-Lussac's equation states that:

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

We are given the following information:

We need to remember that since the temperatures are given in Celsius degrees, we need to convert it to Kelvin (absolute temperature) before use the equation, so:

$P_1=22.5Psi\\T_1=110\°C=110\°C+273.15=383.15K\\T_1=65.9\°C=65\°C+273.15=338.15K$

Now, calculating we have:

$\frac{P_1}{T_1}*(T_2)=P_2\\\\P_2=\frac{P_1}{T_1}*(T_2)=\frac{22.5Psi}{383.15}*338.15=19.86Psi$

Hence, the final pressure is equal to 19.86 Psi.

Have a nice day!

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night. when he took it out, its new volume was 322 milliliters, but its pressure was the same. if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is kelvins.
