Aiken Technical College General Chemistry Discussion

Description

1. match A, B, C, D & E to the physical process occurring.

2. Explain the process of vaporization at the molecular level. Discuss the states of matter in terms of the molecular motion and include information about what happens to the intermolecular interactions during this process.

3. The heat of vaporization for this substance is Delta H vap =298 cal/mol at 80°C. If 882.8 calories are required to completely transform a given amount of the substance form a liquid to a gas, how much material is present? Your answer should be in moles (do not include units in the answer).

4.What is the freezing temperature for this material based on the graph?Enter a numerical answer in degrees Celsius but do not include units.
