Hello!</h2>
The answer is:
The new volume is 2.84 L.

<h2>
Why?</h2>
To solve the problem, we need to remember what STP means. STP means that the gas is at standard temperature and pressure, or 273.15 K (0°C) and 1 atm.
Also, we need to use the Combined Gas Law, since the temperature, the pressure and the volume are being changed.
The Combined Gas Law establishes a relationship between the temperature, the pressure and the volume of an ideal gas using , Gay-Lussac's Law, Charles's Law, and Boyle's Law.
The law is defined by the following equation:

Where,
is the first pressure.
is the first volume.
is the first temperature.
is the second pressure.
is the second volume.
is the second temperature.
So, we are given the following information:

Then, isolating the new volume, and substituting, we have:

Hence, the new volume is 2.84 L.

Have a nice day!

Answer:
By watching the movement of cirrus clouds you can tell from which direction weather is approaching. When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours. Cirrostratus clouds are thin, sheetlike high clouds that often cover the entire sky.
