State Changes Quiz

What is a change of state?

• Transition of matter from one physical form to another

• Change of speed

• Change of shape

• Change of color

Explain the process of heating solids.

• Heating solids involves supplying heat energy to the material, causing particles to vibrate faster and increase in kinetic energy, potentially leading to phase changes.

• Heating solids involves freezing the particles in place.

• Heating solids causes them to shrink in size.

• Heating solids results in the particles losing kinetic energy.

Describe what happens when a solid melts.

• The solid becomes a plasma

• The solid remains unchanged

• The solid turns into a gas

• The solid undergoes a phase transition from solid to liquid.

How does a liquid boil?

• A liquid boils when its molecules gain enough energy to overcome intermolecular forces and change into a gas.

• A liquid boils when it freezes.

• A liquid boils when it solidifies.

• A liquid boils when it evaporates.

What occurs when gases are cooled?

• Ionization or dissociation

• Condensation or solidification

• Melting or vaporization

• Evaporation or sublimation

Define the process of freezing liquids.

• The process of freezing liquids is the transformation of a liquid into a solid state by reducing its temperature below the freezing point.

• The process of freezing liquids is boiling the liquid at a high temperature.

• Freezing liquids involves turning the liquid into a gas state.

• Freezing liquids is achieved by adding heat to the liquid.
