Question 1 (1 point) Saved A freezing point of a substance is the same temperature as the melting point of the substance. True False Question 2 (1 point) Temperature and kinetic energy are directly proportional to one another. For example, as T increases, KE also increases. True False Question 3 (1 point) A solution will always have a higher freezing point than a pure solvent. True False Question 4 (1 point) When graphing your temperature and time data, which measurement...
