The calculated temperature is 289.37 K
According to Gay-Law, Lussac's an ideal gas's pressure is inversely proportional to its absolute temperature when the gas' volume is constant. In other words, according to Gay-Law, Lussac's the pressure of a certain quantity of gas at a fixed volume is directly proportional to the gas's kelvin temperature.
For every 10 degrees that the temperature drops, the inflation pressure in tires typically decreases by 1 to 2 psi.
This is an illustration of Gay-law, Lussac's which states that at constant volume, pressure and Kelvin temperature are directly related. P1/T1=P2/T2
P1=7.48 atm
K is the equation to employ.
P2=7.14 atm
T2=?
T1=30.0C+273.15
=303.15
Solve T2 by rearranging the equation to isolate it.
P1/T1=P2/T2
T2= T1T2/P1
7.14 x 303.15/7.48
= 289.37 K
