Question

An airplane cabin is pressurized to 640mmHg what is the pressure inside the cabin in atmosphere

Answer 1

1 atm= 760 mmHg
640mmHg/760mmHg= .84 atm

Answer 2

Answer: 0.84 atmosphere

Step-by-step explanation:

Pressure of the gas is defined as the force exerted by the particles on the walls of the container. It is expressed in various terms like 'mmHg', 'atm', 'kiloPascals' etc..

All these units of pressure are inter convertible.

We are given:

Pressure of the gas = 640 mmHg

Converting this unit of pressure into 'atm' by using conversion factor:

`760mmHg=1atm`

`640mmHg=(1)/(760)* 640=0.84atm`

Thus there will be 0.84 atm.
