QUESTION:

As shown in Fig. P3.22, 0.1 kg of water is contained within a piston-cylinder assembly at \(100^{\circ} \mathrm{C}\). The piston is free to move smoothly in the cylinder. The local atmospheric pressure and acceleration of gravity are \(100 \mathrm{kPa}\) and \(9.81 \mathrm{~m} / \mathrm{s}^2\), respectively. For the water, determine the pressure, in kPa, and volume, in \(\mathrm{cm}^3\).

ANSWER:

Step 1 of 3

In this question, we need to find the pressure in $kPa$ and volume in $c{m}^{3}$ for water

Considering the figure given

Data given

Mass of water ${m}_{w}=0.1\ kg$

Mass of piston $m=50\ kg$

$A=0.01\ {m}^{2}$

Temperature of assembly $T=10{0}^{0}C$

Atmospheric pressure ${P}_{atm}=100\ kPa$

Gravitational force constant $g=9.81\ m/{s}^{2}$
