F. Answer the following in detail.
1. Describe a simple activity to show that matter has mass.
2. How are molecules in a liquid arranged?
3. List the general properties of solids.
4. Distinguish between the properties of a liquid and a gas.
Answers
Explanation:
1. Matter is anything that has mass and takes up space. So, in order to prove that air is matter, we need to prove that air has mass and takes up space. ... We can show that the air in the balloon has mass by building a balance.
2. Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
3. 1 Answer
A solid has a definite shape and volume.
Solids in general have higher density.
In solids, intermolecular forces are strong.
Diffusion of a solid into another solid is extremely slow.
Solids have high melting points.
4A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance.
