21C to 78C
At 78°C, the substance is in the liquid state. This is because its temperature is higher than its melting point, causing it to change from a solid to a liquid.
35 c
The melting point of the epoxide of benzalacetophenone, commonly known as benzalacetophenone oxide, is approximately 90-95 degrees Celsius.
80 degrees Celsius
Upon Review of the question: THIS ANSWER IS FOR THERMOSTAT TEMPERATURES, NOT AVERAGE RUNNING TEMPERATURE, IF THEY ARE ANY DIFFERENT. 1990s 5th Generation Accords: Open 169-176. Full open: 194. Therefore I believe that the 180-degree thermostats are what you want, but I'm not sure if the stamped-on temperature is opening temperature or running temperature?? 180F ~=83Celcius, so get close to that. 78C = 172F, about the opening temperature.
Yes, cyclohexane will freeze if placed in dry ice. The freezing point of cyclohexane is around 6.5°C, which is well above the temperature of dry ice (-78.5°C). When exposed to dry ice, cyclohexane will solidify into a crystalline form.

Nothing I can think of. Maybe something really esoteric, but common chemicals don't boil at that exact temperature. The two closest common chemicals are hexane (68.7C) and carbon tetrachloride (76.7C). Ethyl alcohol's boiling point is about 78C. Isopropanol boils at 82.6C.
Liquid alcohol will change to vapor when its temperature reaches its boiling temperature. When alcohol reaches its boiling temperature, each molecule of alcohol has enough energy to separate from each other, so each molecule can move freely. The boiling point of liquid alcohol is 351K or 78C
The boiling point of a mixture of alcohol and water depends on the ratio of the two substances. For example, a solution of 20% alcohol and 80% water will have a boiling point higher than either pure alcohol or water. The boiling point elevation is due to the interactions between the alcohol and water molecules.
When mixed with water, carbon dioxide forms carbonic acid. It should be noted it only partially dissolves. If temperatures dip below -78c, it will become solidified again.
