A gas is held at 3.8 atm and 500 K. If the pressure is then decreased to 1.2 atm, what will the new temperature be?
The final temperature will be
This question involves Gay-Lussac's law to answer, which states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
This means that as the pressure goes up, the temperature also goes up, and vice-versa.
The equation to use is:
Rearrange the equation to isolate
