Agas has a volume of 25.6 l at a temperature of 278 k. what will be the new temperature, in c, if
the pressure is kept constant and the volume is decreased to 16.2 l?

The answer is: -97.37° C

According to the Charles and Gay-Lussac's Law we have that:

Where:

v is the volume of the gas

t is the temperature of the gas

k is the proportionality constant

From the Gay-Lussac's Law we also have the following relation:

Since we need to find the new temperature (T2) we can use the last equation:

We are asked to find the temperature in Celsius degrees, so, we must convert the result (in K) to Celsius degrees:

So, the temperature is -97.37° C

Have a nice day!

catya your not at all which answer i've seen you do this on another question!
