What is the new pressure in your tires

Reference no: EM13521742

Before embarking on a car trip from Michigan to Florida to escape the winter cold, you inflate the tires of your car to a manufacturer-suggested pressure of 36 psi while the outside temperature is 27 °F and then make sure your valve caps are airtight. You arrive in Florida two days later, and the temperature outside is a pleasant 74 °F.

(a) What is the new pressure in your tires, in SI units?

_____kPa

(b) If you let air out of the tires to bring the pressure back to the recommended 36, what percentage of the original mass of air in the tires will you release?

____%
