Question

Tire pressure gauges are often caLiBrated in pounds per square inch. An automobile tire is inflated to a pressure of 28.9 psi. Express this pressure in atmospheres and in millimeters of mercury (mmHg).

Answer 1

The pressure of 28.9 psi is equivalent to 1.965 atmospheres using the conversion factor 1 atmosphere = 14.7 psi. In millimeters of mercury (mmHg), it is 1492.4 mmHg by multiplying 1.965 atmospheres by 760 mmHg.

Step-by-step explanation:

To convert the pressure of 28.9 psi to atmospheres, we can use the conversion factor: 1 atmosphere = 14.7 psi. So, we can divide 28.9 psi by 14.7 psi to get the pressure in atmospheres: 28.9 psi / 14.7 psi = 1.965 atmospheres. To convert the pressure to millimeters of mercury (mmHg), we can use the conversion factor: 1 atmosphere = 760 mmHg. So, we can multiply 1.965 atmospheres by 760 mmHg to get the pressure in mmHg: 1.965 atmospheres * 760 mmHg = 1492.4 mmHg.
