Dina is observing a sample of copper metal after it was removed from a flame. She noticed that the temperature decreased. What conclusions could she draw from this observation? 1. The average kinetic energy decreased. 2. The average kinetic energy remained the same. 3. The motion of the particles increased. 4. The motion of the particles stayed the same.
