Exploring the Physical Property of Solubility

Which of the following is a physical property of matter?

• Toxicity

• Flammability

• Density

• Reactivity

Why is solubility considered a physical property?

• It does not change the bonds between atoms.

• It involves a change in the state of matter.

• It produces a new substance.

• It changes the chemical composition of the substance.

What is the first step in dissolving a sugar crystal?

• Heating the sugar

• Breaking it down and grinding it up

• Mixing it with another substance

• Adding a catalyst

What happens to the sugar molecules when they are dissolved in water?

• They form a new compound with water.

• They remain as sugar molecules but are separated.

• They rearrange their atomic bonds.

• They change into a different substance.

What remains unchanged when sugar dissolves in water?

• The temperature of the solution

• The arrangement of water molecules

• The shape of the sugar molecules

• The bonds between water molecules

What is observed when sugar dissolves in water?

• The sugar molecules change shape.

• A chemical reaction occurs.

• The sugar molecules are surrounded by water molecules.

• The water molecules bond with sugar molecules.

What is a key characteristic of a physical property of matter?

• It changes the substance into a different substance.

• It can be observed without changing the substance.

• It involves a chemical reaction.

• It always involves a change in temperature.

When sugar is mixed with water, what happens to the water?

• It becomes a different substance.

• It remains as water.

• It bonds with sugar to form a new compound.

• It evaporates.

What does not change when substances are mixed together?

• The location of molecules

• The shape of molecules

• The state of matter

• The arrangement of molecules

What is the main takeaway about solubility from the video?

• It involves a change in the atomic structure.

• It is a physical property because the substance remains the same.

• It changes the substance into a new one.

• It is a chemical property.
