This question is from the Nearpod: Matter Topic 2 Lesson 2 Textbook pages. The graph shows approximately how the temperature of solid ice changes as it melts into liquid water. How long did it take for the ice to completely melt once it reached the melting point?

• 10 minutes
• 5 minutes
• 15 minutes
• 20 minutes

When objects melt, are they gaining or losing energy?

• gaining
• losing

This question is from the Nearpod: Matter Topic 2 Lesson 2 Textbook pages. The graph shows a substance changing from a liquid to a solid. Based on the graph, what is the value of the freezing point for this substance?

• 1060 degrees Celsius
• 1061 degrees Celsius
• 1062 degrees Celsius
• 1064 degrees Celsius

This question is from the Nearpod: Matter Topic 2 Lesson 2 Textbook pages. The graph shows a substance changing from a liquid to a solid. Think about what would happen if the substance were in the solid phase first, then melted into a liquid. What can you say about the solid's melting point compared to the liquid's freezing point?

• The melting point of the solid is the opposite as the freezing point of the liquid
• The melting point of the solid is the same as the freezing point of the liquid
• The melting point of the solid is not related to the freezing point of the liquid
• This graph does not show the answer to this question
