Answer:
C 30 degrees after 25 minutes
Explanation:
A reaction is exothermic if heat is evolved as the reaction proceeds. How do we know if heat was given out in the course of the reaction? We have to measure the temperature of the system using a thermometer as the reaction progresses.
If the temperature becomes higher than room temperature (25 degrees), we can now conclude that the reaction is exothermic and heat was indeed given out during the course of the reaction.
Answer:
A thermoplastic is any plastic material with a low melting point that becomes molten when heated, solid when cooled, and can be re-melted or molded after cooling. The curing process is completely reversible, and doing so will not compromise the material's physical integrity.
