What is the physical state of tungsten (solid, liquid, or gas) at a temperature of 5993K if the melting point of tungsten is 6182 degrees * F and the boiling point is 10100°F?
What is the state of an alkane with 25 carbons at room temperature and pressure?
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...
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?
Liquid water at room temperature is placed in a syringe, which is then sealed. The plunger of the syringe is drawn back, and at some point bubbles of H2 O vapor are formed. Explain why we can state that the water is boiling.
