Answers
Answer:
I) the correct sick of each material before placing them on water is dry because water will make them wet
ii) when you squeeze each material the water will come out as the water because the materials was filled up of water ( example sponge or any material that absorbs water)
iii) materials like spawn napkin paper towel face cloth paper cotton ball are absorb water because they are made up of porus material
fourth )water repellent material do not absorb water for example plastic and Aluminium material do not attract water molecule aluminium plastic do not has space for water to move like felt and paper
Answer:
1) They were still dry, and some of them weren't going to be discarded. Although the materials have not been submerged in water, they are still dry, and some, such as paper, will not be ruined.
2)Water will come out of each substance when you press it since it was filled with water.
For example, a sponge or any other material that absorbs water.
3) Things like spawn napkins, paper towels, face cloths, and cotton balls absorb water since they are made of porous material.
4) Water resistant materials, such as plastic and aluminium, do not absorb water and do not attract water molecules.
Aluminium plastic, like felt and paper, does not have place for water to migrate.
