12. Which state of matter has indefinite shape and is compressible? 13. All of the following can be considered physical properties EXCEPT: Taste,color, flammability, density, boiling point 14. Melting point can be defined as the temperature when a solid becomes a liquid. The melting point of the chemical acetone is -95°C. Which state of matter would you expect to exist for acetone at a temperature of -94°C? 15. Consider the following specific heats of metals. Metal Specific Heat (J/g∙°C) Aluminum...

Acetylsalicylic acid reacts very, very slowly with water at room temperature and will eventually decompose to produce salicylic acid. At temperatures >100oC, this reaction becomes very fast. If your product isn’t completely dry when you attempt to determine melting point, what will happen in the capillary tube? What temperature would you expect for melting point in that situation?

The third law of thermodynamics relates the entropy (randomness) of matter to its absolute temperature. Which of the following statements are in agreement with the third law of thermodynamics? Check all that apply. Check all that apply. At absolute zero, the interatomic distance within a crystal is minimized. As the temperature of a perfect crystal increases, the random vibrations of the molecules decrease. At zero degrees kelvin, substances maximize entropy. In a gaseous state, the entropy of the system is...
