 Question #1

What are the approximate melting points of the substances B and E?

Melting Points for B = 350° C, for E = 1200° C.

Question #2

This model can simulate a substance that does not have a melting point.

Find that substance and click Take snapshot to show what substance it is.

Describe why it does not have a boiling point, and how you know that it doesn't.

(You can use the drawing tool for your answer.)

Question #3

Make up a rule that describes how boiling point changes with the strength of particle attraction. Use evidence from the model to justify your rule.

The boiling point gets higher when there is a stronger particle attraction.

Question #4

What additional questions do you have about this model?

How do you tell the melting point vs the boiling point.
