FranA volume empty of free molecules refers to a vacuum, where there are no gas molecules present. In a perfect vacuum, all matter has been removed, leaving behind a space that is devoid of any particles. Such environments are commonly used in scientific experiments and industrial processes.

Is it true that liquids have a large portion of empty volume between molecules?
Yes, liquids typically have molecules that are close together but still have spaces between them. This is why liquids can flow and take the shape of their container. The arrangement of molecules in liquids allows them to move past each other while maintaining some level of cohesion.
What is the volumes of gas molecules relative to the total gas volume?
The volume of gas molecules is negligible compared to the total gas volume. Gas molecules themselves occupy a very small fraction of the total volume of the gas, with the majority of the volume being empty space between the molecules.
When you add 5ml of sugar to 250ml of coffee the volume is still 250ml?
The addition of 5ml of sugar to 250ml of coffee should increase the total volume to 255ml, not remain at 250ml. Mixing two substances typically leads to an increase in total volume due to the added volume of the sugar.
Do gas molecules have definite shape and volumes?
Gas molecules do not have a definite shape or volume. They take the shape and volume of the container they are in, as they are free to move and fill the available space.
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.
