Question

A car driver measures a tire pressure of 320 kPa. What is the absolute pressure in the tire?(A) 0 kPa (B) 219 kPa (C) 101 kPa (D) 421 kPa (E) 320 kPa

Answer 1

(D) 421 kPa

Step-by-step explanation:

The absolute pressure of the tire is equal to the pressure measured plus the atmospheric pressure of 101 kPa. Then, the absolute pressure is

P = 320 kPa + 101 kPa

P = 421 kPa

So, the answer is

(D) 421 kPa
