For the Greater Good Science Center, âdiversityâ refers to both an obvious fact of human lifeânamely, that there are many different kinds of peopleâand the idea that this diversity drives cultural, economic, and social vitality and innovation. When substances are heated, the molecular bonds between their particles are weakened, and the particles move faster, causing the substance to expand.
