Answer:
d. the strength of the forces between its atoms
Step-by-step explanation:
The strength of the intermolecular forces between the atoms of the pure substance will determine the type of substance it is when heated to 100°C.
- A pure substance are elements and compounds.
- They are usually homogenous in all parts with a definite composition.
- A solid is made up of strong intermolecular forces that are very difficult to break.
- Liquids have fairly weak bonds between them.
- Gases have little to no intermolecular attraction.
- Using these parameters, we can see that the property of the substance at this temperature will determine its physical state.
