Unit 2 SOL Review

When do the water molecules in the ice cubes have their lowest particle motion?

• After the ice cubes fully melted into a pitcher of lemonade

• Before the ice cubes are placed into a pitcher of lemonade

• While the ice cubes are melting in a pitcher of lemonade

• The particle movement does not change

A researcher conducts an experiment to study phase changes between ice, water, and water vapor. He graphs his observations, as shown. Which correctly interprets information from the graph?

• Between 0°C and 100°C water is in its solid form (ice)

• At line segment DE: water is in its gas form (water vapor)

• At line segment BC: water is in its solid form (ice)

• At -20°C water is in its liquid form (water)

Image 1 shows hot liquid particles on the left and cold particles on the right with a barrier between the two particles. The large spheres represent the cold particles and the small spheres represent the hot particles. In Image 2, the barrier has been removed and time has passed.

Analyze the images and choose the statement that best describes what is happening with the thermal energy.

• Thermal energy is transferring from the cold liquid particles to the hot particles

• Thermal energy is transferring from the hot liquid to the cold solid particles

Image 1 shows hot liquid particles on the left and cold particles on the right with a barrier between the two particles. The large spheres represent the cold particles and the small spheres represent the hot particles. In Image 2, the barrier has been removed and time has passed.

Analyze the images and choose the statement that best describes what is happening with the thermal energy.

• The average kinetic thermal energy of the cold particles has increased

• The average kinetic energy of the hot particles has increased.
