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

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

Answer 2

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

Explanation :

As we know that,

$1atm=101325\frac{N}{m^2}\\\\(1\frac{N}{m^2}=1Pa)\\\\101325\frac{N}{m^2}=101325Pa\\\\(1KPa=1000Pa)\\\\101325Pa=101.325KPa$

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

$4KPa=4\times 1000Pa=4000Pa\\\\16\frac{N}{m^2}=16Pa\\\\311\frac{N}{m^2}=311Pa$

Thus, the measurements in order of increasing pressure is,

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