Answer 1

Gɪᴠᴇɴ ;-

Case - 1 ;-

Volume of a fixed mass of gas is 750 cm³ at -23°C.

\begin{gathered}\longmapsto\:\:\bf{V_1\:=\:750\:cm^3\:} \\ \end{gathered}

⟼V

1

=750cm

3

$\begin{gathered}\longmapsto\:\:\bf{T_1\:=\:-23°C\:=\:-23\:+\:273\:=\:250\:K} \\ \end{gathered}$

⟼T

1

=−23°C=−23+273=250K

Pressure is 800 mm.

$\begin{gathered}\longmapsto\:\:\bf{P_1\:=\:800\:mm\:} \\ \end{gathered}$

⟼P

1

=800mm

CASE - 2 ;-

$\begin{gathered}\longmapsto\:\:\bf{V_2\:=\:720\:cm^3\:} \\ \end{gathered}$

⟼V

2

=720cm

3

$\begin{gathered}\longmapsto\:\:\bf{T_2\:=\:-3°C\:=\:-3\:+\:273\:=\:270\:K} \\ \end{gathered}$

⟼T

2

=−3°C=−3+273=270K

Tᴏ Fɪɴᴅ ;-

The pressure (P₂) of the gas in case-2.

$\begin{gathered}\bf\blue{We\:know \:that,} \\ \end{gathered}$

Weknowthat,

☆ According to equation of gas in terms of pressure (P), absolute temperature (T) & volume (V) is

$\begin{gathered}\red\bigstar\:\:{\underline{\orange{\boxed{\bf{\green{\dfrac{P_1\:V_1}{T_1}\:=\:\dfrac{P_2\:V_2}{T_2}\:}}}}}} \\ \end{gathered}$

=900mm

\begin{gathered}\Large\bf\orange{Therefore,} \\ \end{gathered}

Therefore,

The pressure of the gas in case-2 is 900 mm.
