Question

the air pressure in a volleyball is 75 psi. what is this pressure in torr? (1 atm = 14.7 psi) 75000 torr 520 torr 7600 torr 562 torr 3900 torr

Explanation:

Step1: Convert psi to atm

We know that \(1\ atm = 14.7\ psi\). So, to convert \(75\ psi\) to \(atm\), we use the formula \(P_{atm}=\frac{P_{psi}}{14.7}\).

$$P_{atm}=\frac{75}{14.7}\ atm\approx5.102\ atm$$

Step2: Convert atm to torr

Since \(1\ atm = 760\ torr\), to convert the pressure from \(atm\) to \(torr\), we use the formula \(P_{torr}=P_{atm}\times760\).

$$P_{torr}= 5.102\times760\ torr\approx 3900\ torr$$

Answer:

3900 torr
