Most cars need tires filled to 32.0 - 35.0 psi. Your tires are filled to 32.1 psi at the beginning of the month where the temperature is on average 12.5 degree C. At the end of the mounth the average temperture has dropped to -3.1 C. Are the tires still safe to drive on?

No it is not safe to drive on.

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=32.1psi\\T_1=12.5^0C=(273+12.5)K=285.5K\\P_2=?psi=27.5psi\\T_2=-3.1^0C=(273-3.1)K=269.9K$

Putting values in above equation, we get:

$\frac{32.1}{285.5K}=\frac{P_2}{269.9}\\\\P_2=30.3psi$

As the pressure lies below the recommended range of 32.0-35.0 psi. Thus it is not safe to drive on

Answer from: Quest

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
