1.1. Thermoplastics

Try these first

1. 1.

   What are thermoplastics?

   Hint

   Think about their behavior when exposed to heat.

2. 2.

   Name one common application of thermoplastics.

   Hint

   Recall the materials mentioned earlier.

3. 3.

   What are thermoplastics?

   • Plastics that cannot be reshaped
   • Plastics that can be reshaped when heated
   • Plastics that are only used for packaging

   Hint

   Think about how they behave when heated.

4. 4.

   True or False: Thermoplastics undergo a permanent chemical change when heated.

   • True
   • False

   Hint

   Recall the properties we discussed.

5. 5.

   Imagine you're designing a new piping system using thermoplastics. What factors would you consider in terms of mechanical properties and environmental sustainability?

   Hint

   Think about both structural integrity and the end-of-life of the material.

6. 6.

   Evaluate the use of thermoplastics in civil engineering. What engineering aspects must be addressed during their application?

   Hint

   Consider both physical design and ecological impacts.
