Temperature and Changes of State QzL

Yassin and Logan are observing a pot of water being heated on the stove. How can the changes they observe in the water's temperature or state be described in terms of particles?

• Particles transferring energy

• Particles losing mass

• Particles changing color

• Particles becoming larger

Madeleine and Logan are conducting an experiment to identify a substance based on its melting and boiling point. What should they recognize about the substance in relation to these points?

• Its color

• Its state

• Its mass

• Its volume

Logan and Madeleine are observing ice melting into water. What should they be able to explain in terms of changes to the energy of the particles?

• Changes of state

• Changes of color

• Changes of mass

• Changes of volume

Yassin and Ivy are conducting an experiment to observe changes of state in their science class. What type of diagrams should they draw to explain their observations?

• Before and after diagrams

• Color diagrams

• Mass diagrams

• Volume diagrams

During a science experiment, Ivy and Nicolas observed a block of ice turning into water. What is this process called when a substance changes from a solid to a liquid state?

• Freezing

• Melting

• Evaporation

• Condensation

Akeem and Ivy were making ice cream at home. They poured the liquid mixture into molds and placed them in the freezer. What is the change of state from liquid to solid known as?

• Melting

• Boiling

• Freezing

• Sublimation

Madeleine and Yassin are conducting an experiment to find out at what temperature liquid water freezes. What temperature should they observe?

• 100 °C

• 0 °C

• 50 °C

• -10 °C

Alexis and Logan are making ice cubes from water. Name the two states involved in freezing.

• Gas and Liquid

• Solid and Gas

• Liquid and Solid

• Plasma and Liquid

Nicolas and Ivy are observing an ice cube melting on a warm day. What happens to the particles of the ice cube as it melts?

• They stop moving.

• They vibrate slower.

• They move away from their places.

• They become larger.

During a science experiment, Alexis and Logan observed an ice cube melting in a warm room. What causes the particles in the ice cube to vibrate faster as it melts?

• The ice itself generates energy.

• The surroundings transfer energy to the ice.

• The particles lose energy.

• The ice absorbs light.
