1.	What volume of air will be expelled from a vessel containing 400 cm3 at 7oC when it is heated to 27oC at the same pressure?
Answer» \(\frac{V_1}{T_1}=\frac{V_2}{T_2}\) i.e, \(\frac{400\,cm^3}{(273+7)K}\) = \(\frac{V_2}{(273+27)K}\) or V₂ = \(\frac{400}{280}\) x 300 cm³ = 482.6 cm³ This is volume after expansion. \(\therefore\) Volume expelled = (428∙6 - 400) cm³ = 28∙6 cm³

What volume of air will be expelled from a vessel containing 400 cm3 at 7oC when it is heated to 27oC at the same pressure?

Answer»

\(\frac{V_1}{T_1}=\frac{V_2}{T_2}\) i.e, \(\frac{400\,cm^3}{(273+7)K}\) = \(\frac{V_2}{(273+27)K}\)

or V₂ = \(\frac{400}{280}\) x 300 cm³ = 482.6 cm³

This is volume after expansion.

\(\therefore\) Volume expelled

= (428∙6 - 400) cm³

= 28∙6 cm³
