Hanrietta has a sample of a pure substance in a beaker. She heats the substance to a temperature of 100C. What will determine if the substance is a solid, liquid, or gas at 100C? .a. the amount of it that is contained in the beaker . b. the height of the beaker containing it. c. the width of the beaker containing it. d. the strength of the forces between its atoms

d. the strength of the forces between its atoms

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.
