Question

The physical quantity denoted by mass into pressure by density

Answer 1

It is work
As, mass × pressure/ density
=mass×pressure/mass÷volume
(now mass gets cancelled and pressure and volume is multiplied )
so pressure ×volume= work

Answer 2

Given :

$\frac{Mass * Pressure}{Density}$

To Find :

The physical quantity denoted by $\frac{Mass * Pressure}{Density}$

Solution :

Formula for Pressure = $\frac{Force}{Area}$

Formula for Density = $\frac{Mass}{Volume}$

Formula for Volume = Area × Length

∴ $\frac{Mass * Pressure}{Density}$

=  $\frac{Mass * Force * Volume}{Area * Mass}$

= $\frac{Force * Area * Length}{Area }$

= Force × Length

We know, Work is measured as the scalar product of the applied force and the displacement of the object.

  Work Done = Force . Displacement

Therefore, the physical quantity having $\frac{Mass * Pressure}{Density}$  is Work.
