Based on the kinetic theory of gases, absolute zero temperature is reached when___________________?
Show answer Hide answer
Answer: C. kinetic energy of the molecules is zero
Explanation
According to the kinetic theory of gases, absolute zero temperature is reached when energy is zero. At this theoretical point, the thermal kinetic energy of gas molecules becomes completely zero. Molecular motion ceases entirely, which corresponds to the zero point on the Kelvin scale. Kinetic theory relates macroscopic gas temperature directly to microscopic molecular motion. Thermal energy is proportional to the average translational kinetic energy of gas particles. Absolute zero represents minus two hundred seventy-three point fifteen degrees Celsius.
Cryogenic research explores material behaviors as temperatures approach absolute zero limits. Superconductivity and superfluidity phenomena occur at extreme temperatures near absolute zero. Thermodynamic property extrapolations rely on kinetic theory models for ideal gas behavior. Option A suggests gas volume is zero, which is physically impossible due to atomic dimensions. Option B states pressure is zero, which is a consequence of zero kinetic energy rather than the definition. Option D refers to specific heat vanishing, which does not define the fundamental temperature origin.
