Activity #6 States of Mater and Intermolecular Forces

#1 Converting to Kelvin

• 0 degrees farenheit = 255.37 Kelvin
• 32 degrees farenheit = 273.15 Kelvin
• 70 degrees farenheit = 294.26 Kelvin
• 212 degrees farneheit = 373.15 Kelvin

#3 What atoms are attracted at 0 K?

Each water molecule is two hydrogen atoms bonded to one oxygen atom, and because of how the atoms share electrons a water molecule is slightly positively charged at the hydrogen atoms and negatively charged at the oxygen atom.  So when we talk about hydrogen bonding its the molecules need to attract the oppositely charged ends of other water molecules.  In the simulation they appear to be creating circle patterns with the hydrogens trying to connect to the oxygen atoms and are close together but still have space inbetween.

#4 Give a temp and pressure required to make oxygen a liquid.

For my simulation I fluctuated between 14 and 21 ATM rapidly and was at about 198 K when i noticed oxygen going from a gas to a liquid.
