An automobile tire is inflated with air originally at $10\mathrm{.}0C$ and normal atmospheric pressure. During the process, the air is compressed to $32\mathrm{.}0\%$ of its original volume and the temperature is increased to $39\mathrm{.}0C.$

$($a$)$ What is the tire pressure in pascals?

$($b$)$ After the car is driven at high speed, the tire's air temperature rises to $85\mathrm{.}0C$ and the tire's interior volume increases by $3\mathrm{.}00\%.$ What is the new tire pressure $($absolute$)$ in Dascals?
