Question

If the pressure of a gas is 2.42 atm, what is its pressure in kPa?

Answer 1

Answer: The pressure in kilo pascals will be 245.206kPa

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 = 2.42 atm

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

1 atm = 101.325 kPa

`\Rightarrow 2.42atm* ((101.325kPa)/(1atm))\\\\\Rightarrow 245.206kPa`

Hence, the pressure in kilo pascals will be 245.206kPa

Answer 2

Pressure is defined as the force that is being exerted by any substance per any unit area. For a gas, it is the force that the gas particles exert on the container walls. Atm or atmosphere and Pa or pascals are units pressure. There is 101325 Pascals or 101.325 KPa in 1 atm. Hence 2.42 atm is equivalent to 248,246.25 Pa or 248.246 KPa.
