Is it true that liquids have a large portion of empty volume between molecules?
Well, not ''large'' but yes there is empty volume between them.
When you add 5ml of sugar to 250ml of coffee the volume is still 250ml?
When sugar is dissolved in coffee, the sugar molecules is fitted inside the empty spaces in the water molecules. This means that the volume of coffee does not increase.
Do gas have a definite volume yes or no?
No. A gas will fill any available volume by expanding and thereby reducing its pressure.Conversely, reducing the volume of a container of gas will increase the density of the molecules, which is increasing the pressure.No, one of the characteristics of a gas is that it does not have a definite volume but expands to fill its container.
What happens to the mean free path of the molecules in this process if a helium filled balloon initially at room temperature is placed in a freezer will its volume increase decrease or remain the same?
The volume decrease.
Why are liquid almost incompressible?
Yes. Gases are very compressible because there is a lot of empty space between the molecules. A liquid has almost no empty space between the molecules. When compressing a gas you are pushing the molecules closer together, getting rid of some of the empty space. Can't do that with liquids. Example 18grams of liquid ware will occupy 18 ml or 0.018 Liter of space (volume). Boil that same 18 grams of water and it will occupy about 24000 ml or 24 Liters of space because in the gas form the same number of molecules are farther apart with lots of empty space between them .

Why can we state that most of the volume of matter such as the tabletop you are writing on is actually empty space?
Because the space between atomic particles, atoms and molecules is empty.

When sugar is dissolved in coffee, the sugar molecules is fitted inside the empty spaces in the water molecules. This means that the volume of coffee does not increase.
What is the volume of an empty stomach?
The volume of an average adult's empty stomach is 1/5 of a cup.
Molecular structure of natural gas?
The molecules are not bound making them free to move around. They have no definite shape or volume.
Do gas have a definite volume yes or no?
No. A gas will fill any available volume by expanding and thereby reducing its pressure.Conversely, reducing the volume of a container of gas will increase the density of the molecules, which is increasing the pressure.No, one of the characteristics of a gas is that it does not have a definite volume but expands to fill its container.
How can you demonstrate ther is space between molecules of water?
Calculate volume of molecule, calculate mass of molecule, compare to bulk density. Lower bulk density indicates empty space.

The volume decrease.

Can the removing of energy increase the volume of a substance because the molecules come closer together?
No. It can increase the volume in some cases, but not BECAUSE the molecules come closer together. If the molecules come closer together, the volume will DECREASE.
What is the volume of a empty coffee mug?
0oz
What is the empty space where gas molecules are not located?
The empty space could be filled with liquid or solid matter.
