Boiling QzL

What is the process called when a liquid turns into vapor upon heating?

• Freezing

• Condensation

• Boiling

• Melting

How can changes of temperature or state be described?

• In terms of particles transferring energy

• By the color of the substance

• Through the size of the particles

• By the weight of the substance

What should you recognize about the state of a substance?

• Its color and texture

• Its melting point and boiling point

• Its weight and volume

• Its density and mass

How can changes of state be explained?

• By changes to the energy of the particles

• By the shape of the container

• By the color of the substance

• By the smell of the substance

What happens to a substance when it is boiling?

• It changes from a solid state to a liquid state.

• It changes from a liquid state to a gas state.

• It changes from a gas state to a solid state.

• It remains in the liquid state.

Which model can be used to explain boiling?

What forms throughout the liquid when water boils?

• Ice crystals

• Bubbles of steam

• Solid particles

• Liquid droplets

How are water particles arranged in the liquid state?

• Spread far apart

• Touching their neighbors

• Randomly scattered

• In a fixed position

What happens to water particles inside the bubbles when water boils?

• They freeze

• They are spread far apart

• They condense

• They form a solid

What is required for boiling to occur?
