Answer :
Charles's Law : It is defined as the volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
Mathematically,
[tex]V\propto T[/tex]
Boiling water bath Cool bath 1 Cool bath 2
Temperature (⁰C) 99 17 2
Temperature (K)(T) 273+99=372 273+17=290 273+2=275
Volume of water 0.0 27.0 34.0
in cool flask (mL)
Volume of water= 135.8 135.8 135.8
Air in flask (mL)
Volume of air 135.8 108.8 101.8
in cool flask (V)
[tex]\frac{V}{T}[/tex] [tex]\frac{135.8}{372}=0.365[/tex] [tex]\frac{108.8}{290}=0.375[/tex] [tex]\frac{101.8}{275}=0.370[/tex]
The graph volume versus temperature for a gas is shown below.
