The average speeds of gas molecules in cylinders A, B, C, and D are 0.01 m/s, 0.005 m/s, 0.1 m/s, and 0.5 m/s, respectively. Which cylinder contains gas that is closest to absolute zero?
We can relate the average speed
of the gas molecules by its kinetic energy. The kinetic energy is the work done
by the object due to its motion. It is represented by the formula of the half
the velocity squared multiply by the mass of the object. The absolute zero
theory is the assumption that at 0 Kelvin or -273.15 degrees Celsius, the gas
molecules stop moving. It is because the temperature is severely cold enough to
allow movement of the gas molecules. The gas molecule that is closest to the
absolute zero is in cylinder B because it moves so slow and its movement is
almost near to the absolute zero theory.
