1.4. Under Revision

Try these first

1. 1.

   What does compressibility refer to?

   Hint

   Think about how materials might react when squeezed.

2. 2.

   Define the Swelling Index (C).

   Hint

   Consider how wet materials behave compared to dry ones.

3. 3.

   What does compressibility measure?

   • Change in temperature
   • Volume reduction under pressure
   • Color change

   Hint

   Think about materials under physical stress.

4. 4.

   The Swelling Index indicates what?

   • True
   • False

   Hint

   Consider how certain materials change when they get wet.

5. 5.

   Given a material with a swelling index of 4, calculate expected changes in compressibility under varying moisture conditions few examples.

   Hint

   Consider base comparisons with a material that has a swelling index of 2.

6. 6.

   Analyze a stress-compressibility graph and predict the behavior of a material under increasing load.

   Hint

   Relate it back to the definitions of compressibility and the properties of the material in focus.
