Question

1) contracts
2) is stronger
3) is more porous
4) is less brittle

Answer 1

Using less water for mixing plaster of Paris will result in weaker set plaster.

Step-by-step explanation:

Using less water for mixing plaster of Paris will result in set plaster that is weaker.

Plaster of Paris is a type of gypsum plaster that undergoes a chemical reaction called hydration when water is added. This reaction leads to the formation of gypsum crystals, which give plaster its strength. If there is not enough water, the reaction may not be complete, resulting in a weaker and less durable plaster.

It is important to follow the recommended water-to-plaster ratio to ensure the optimal strength and quality of the set plaster.
