Consider the heating curve.
A graph of temperature versus time, with time in minutes as the horizontal axis and temperature in degrees Celsius as the vertical axis. 5 sections of line are labeled: 1 from 0 minutes, negative 50 degrees to 1, 0 degrees. 2: from 1, 0 to 5, 0. 3: from 5, 0 to 9, 2200. 4: from 9, 2200 to 17, 2200. 5: from 17.0, 2200 to off the chart at 2,400 degrees.

Particles move fastest where the temperature is highest. Region 5 reaches the greatest temperature, so average particle kinetic energy (and speed) is largest there.
