Question

Rank the measurements in order of increasing pressure.

4 kPa, 16 N/m2, 311 N/m2, 0.3 Pa


16 N/m2, 311 N/m2, 0.3 Pa, 4 kPa
4 kPa, 16 N/m2, 311 N/m2, 0.3 Pa
4 kPa, 311 N/m2, 16 N/m2, 0.3 Pa
0.3 Pa, 16 N/m2, 311 N/m2, 4 kPa

Answer 1

Answer : The correct option is,
`(0.3Pa),(16N/m^2),(311N/m^2),(4KPa)`

Explanation :

As we know that,

`1atm=101325(N)/(m^2)\\\\(1(N)/(m^2)=1Pa)\\\\101325(N)/(m^2)=101325Pa\\\\(1KPa=1000Pa)\\\\101325Pa=101.325KPa`

Now we convert all the given values of the pressure into the Pascal(Pa), we get

`4KPa=4* 1000Pa=4000Pa\\\\16(N)/(m^2)=16Pa\\\\311(N)/(m^2)=311Pa`

Thus, the measurements in order of increasing pressure is,

`(0.3Pa)<(16N/m^2)<(311N/m^2)<(4KPa)`

Answer 2

For the answer to the question above.
The pressure (the symbol "P") is the force per unit area applied in a direction perpendicular to the surface of an object.
This is from least to greatest: 0.3Pa, 16 N/m2, 311 N.m2, 4kPa
