I filled my tires a couple weeks ago and now my tire pressure light is on! I overheard my friend say that it had something to do with the weather change! I'm going to ask my chemistry teacher!
Hi Justin! You came to the right place! In chemistry, there is three different gas laws that we follow. The one that you are describing is Gay-Lussac's law! This law relates temperature and pressure directly. The volume stays constant but the pressure and temperature can be manipulated. When temperature decreases so does pressure!
Hi Mrs. Garceau, I was wondering if you could tell me why my tire pressure light is on when I just put air in my tires?!
Know p1= 103 KPA T1= 298 K T2= 1,201 K Want P2
P1 x T2 = P2 x T1
Equation P1 X T2 = P2 X T1 103 x 1,201 = P2 x 298 123,703 = 298P2 P2 = 415.1 kPa
This is the formula for Gay-Lussacs law! There is an example of how to do one of these problems on the board! Remember: temperature must always be in Kelvin!
