Previous Page Next Page Page 11 of 34 Question 11 (3 points) Saved Which of the two potential energy curves corresponds to a substance with the lower melting point? PE O X, because the particles are further apart and therefore easier to separate and get moving. O X, because the potential well is wider giving the particles more room to move around. Y, because the potential well is not as deep, so it doesn’t require as much energy to get the particles moving to form a liquid. O Y, because it is easier for smaller particles to slide past each other in the liquid phase. Page 11 of 34 Next Page Previous Page
