Question

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​

Answer 1

Answer:

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.
