State whether statements $3\mathrm{.}6-3\mathrm{.}10$ are $($or can be$)$ true or false. For

those that are false, explain why.

$3\mathrm{.}6$ The value for the absolute pressure will always be greater

than that for the gage pressure.

$3\mathrm{.}7$ As long as you stay on the surface of Earth, the atmo$-$

spheric pressure will be $14\mathrm{.}7$ psia.

$3\mathrm{.}8$ The pressure in a certain tank is $-55\mathrm{.}8Pa(\frac{?}{abs}).$

$3\mathrm{.}9$ The pressure in a certain tank is $-4\mathrm{.}65$ psig.

$3\mathrm{.}36$ The pressure at the bottom of a tank of propyl alcohol at

$25C$ must be maintained at $52\mathrm{.}75$ kPa $($gage$).$ What depth

of alcohol should be maintained?

$3\mathrm{.}37$ When you dive to a depth of $12\mathrm{.}50$ ft in seawater, what is

the pressure?

$3\mathrm{.}56$ Determine the pressure at the bottom of the tank in

Fig. $3\mathrm{.}25.$
