Question

Eva pumps up her bicycle tire until it has a gauge pressure of 413 kilopascals. If the surrounding air is at standard pressure, what is the absolute pressure in the bicycle tire? A. 33.9 kPa B. 49.7 kPa C. 312 kPa D. 514 kPa

Answer 1

Answer: D. 514 kPa

Explanation: I got this right on Edmentum.

Answer 2

Answer : The correct option is, (D) 514 kPa

Solution : Given,

Gauge pressure = 413 kPa

Atmospheric pressure = 101.325 kPa

Now we have to calculate the absolute pressure in the bicycle tire.

Absolute pressure = Gauge pressure + Atmospheric pressure

Now put all the given values in this expression, we get the absolute pressure in the bicycle tire.

Absolute pressure = (413kPa) + (101.325kPa)

Absolute pressure = 514.325 kPa = 514 kPa

Therefore, the absolute pressure in the bicycle tire is, 514 kPa
