Aman drove his car through the nevada desert one day when the temperature was over 100°f. when he started the trip, the gas station attendant found the tire to be 32 lb/in2. when he filled up with gas after crossing the desert, an attendant found the tire pressure to be 38 lb/in2. what is the best explanation for the increase in tire pressure?
the road wear on the tire caused a decrease in volume and, therefore, an increase in tire pressure.
the temperature in the tire increased, causing an increased tire pressure.
the hot temperature caused the springs to expand, which allowed more weight to ride on the tires, thus causing more pressure inside.
the measurements of the pressure were inaccurate. the added weight of the gas caused the extra pressure in the tires.

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
