Variation of volume with temperature was first studied by French chemist, Jacques Charles, in 1787 and then extended by another French chemist Joseph Gay-Lussac in 1802. For a fixed mass of a gas under isobaric condition, variation of volume V with temperature t°C is given by V = `V_(0)[l + alphat]` where `V_(0)` is the volume at 0°C, at constant pressure.
1 or every 1° change in temperature, the volume of the gas changes by............... of the volume at `0^(@)` C

Options

A. `alpha` (given above) is called volume coefficient
B. Value of `alpha` is `3.66 xx 10^(-3) ""^(@)C^(-1)` for all gases
C. 273 K is the lowest possible temperature attained
D. Absolute zero is the temperature reached when all possible thermal energy has been removed from a substance

Answer

C
