Question

if volume of an ideal gas at 0 degree centigrade is 546 cm cube What is the volume at hundred degree centigrade?
plz help​

Answer 1

Assume the pressure to be constant.

Given,

• $\sf{T_1=0^oC=273\ K}$

• $\sf{V_1=546\ cm^3}$

• $\sf{T_2=100^oC=373\ K}$

We have to find $\sf{V_2.}$

By Charles's Law,

$\sf{\longrightarrow \dfrac{V_2}{T_2}=\dfrac{V_1}{T_1}}$

$\sf{\longrightarrow V_2=\dfrac{V_1T_2}{T_1}}$

$\sf{\longrightarrow V_2=\dfrac{546\times373}{273}}$

$\sf{\longrightarrow\underline{\underline{V_2=746\ cm^3}}}$

Or,

$\sf{\longrightarrow\underline{\underline{V_2=7.46\times10^{-4}\ m^3}}}$
