Question

An airplane cabin is pressurized to 570 mmhg. what is the pressure inside the cabin in atmospheres?

Answer 1

0.75 atmospheric pressure

Step-by-step explanation:

Pressure, P = 570 mm of Hg

We know that 1 atmospheric pressure = 760 mm of Hg

So, 760 mm of Hg pressure = 1 atmospheric pressure

1 mm of Hg = 1 / 760 atm pressure

570 mm of Hg = 570 / 760 atm

= 0.75 atm

Thus, 570 mm of Hg pressure is equal to 0.75 atmospheric pressure.

Answer 2

1 atm corresponds to 760 mmHg, so we can set up a simple proportion to find how many atmospheres correspond to 570 mmHg:

`1 atm: 760 mmHg = x: 570 mmHg`
and from this, we find

`x= (1 atm \cdot 570 mmHg)/(760 mmHg) =0.75 atm`
