How can Ethan best defend his conclusion? A. by demonstrating that the substance will eventually melt if the temperature continues to increase B. by verifying that the substance is now made up of different molecules than before it was heated C. by verifying that the substance is made up of only one type of element D. by demonstrating that the substance is less dense after it is heated
B. by verifying that the substance is now made up of different molecules than before it was heated
