This heating curve is produced when a certain when a substance is heated. 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 10 degrees to 1, 0 degrees. 2: from 1, 0 to 4, 0. 3: from 4, 0 to 7.5, 100. 4: from 7.5, 100 to 17.5, 100. 5: from 17.5,100 to 19, 120. Which best compares the particles of the substance when it is in region 1 with the particles of the substance when it is in region 3? The particles are slower in region 3. The particles are more orderly in region 1. The particles have more kinetic energy in region 1. The particles have less freedom of motion in region 3.
