Question

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

Explanation:

Step1: Convert psi to atm

We know that \(1\ atm = 14.7\ psi\). Let \(x\) be the pressure in atm. Then \(x=\frac{75\ psi}{14.7\ psi/atm}\approx5.102\ atm\)

Step2: Convert atm to torr

Since \(1\ atm = 760\ torr\). Let \(y\) be the pressure in torr. Then \(y = 5.102\times760\ torr\approx 3900\ torr\)

Answer:

3900 torr
