What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
What the smallest particle of a substance that has all the properties of that substance?
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.

In the volume of a substance in the gaseous state is 1000 times the volume of that substance in the liquid state how much space would ml of that substance in the liquid state take up if it evaporate?
If the volume of the substance in the gaseous state is 1000 times the volume of the substance in the liquid state, this means that 1 ml of the substance in the liquid state would occupy 0.001 ml when it evaporates into a gas.
Is formula C60 a simple molecular substance or a giant covalent structure?
That's a very good question and there are arguments for both. I would class it more as a simple molecular substance because a sample will contain many separate molecules, with forces other than covalent bonds between them. A giant covalent structure like diamond is wholly held together by covalent bonds.
What is the shape of an amorphous substance?
an amorphous substance is something that has a random molecular formation in it's natural form (when solidified). the opposite would be semi-cristaline which has random molecular structure when heated but returns to an organised unifom state when solidified. example. certain polymers
Which substance would be most appropriate to determine whether a substance contains simple sugars such as glucose?
Benedict's solution
What state is a substance in at 1 ATM and -50 degrees Celsius?
The state of a substance at 1 ATM and -50 degrees Celsius would depend on the substance. For most substances, at -50 degrees Celsius and 1 ATM pressure, they would typically be in a solid state.
Which state would the substance be if it had no fixed volume?
The substance would be in a gaseous state if it had no fixed volume. Gases have no fixed shape or volume and can expand to fill the container they are in.
