Due to the friction between a tire and the road surface, the temperature of the air inside a tire increases as one drives. If the tire pressure is 26 psi when the car is in the driveway at 25˚C, what is the temperature of the air inside the tire when the pressure increases to 29 psi? Assume tire volume is constant.

How much heat is added if 0.814g of water increase in temperature by 0.351 degree c?

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.
