1.	A sample of helium has a volume of 500 cm3 at 373 K. Calculate the temperature at which the volume will become 260 cm3 . Assume that the pressure is constant.
Answer» V₁ = 500 cm³ , V₂ = 260 cm³ T₁ = 373 K, T₂ = ? By Charle's Law, \(\frac{V_1}{T_1}=\frac{V_2}{T_2}\) T₂ = \(\frac{V_2T_1}{V_1}\) = \(\frac{263\times373}{500}\) = 196.19 K

A sample of helium has a volume of 500 cm3 at 373 K. Calculate the temperature at which the volume will become 260 cm3 . Assume that the pressure is constant.

Answer»

V₁ = 500 cm³ , V₂ = 260 cm³

T₁ = 373 K, T₂ = ?

By Charle's Law,

\(\frac{V_1}{T_1}=\frac{V_2}{T_2}\)

T₂ = \(\frac{V_2T_1}{V_1}\)

= \(\frac{263\times373}{500}\)

= 196.19 K
