Activity 6

States of Matter and Intermolecular Forces

1)
0*F= 255.3 K
32*F = 273.15 K
70*F= 294.3 K
212*F=373.15 K
2)
3) For a solid and liquid simulation the water molecules slow and huddle closely in the same position as the temperature keeps getting lower. The red atoms are closely connected and don't change through the simulation. In a gas simulations the water molecules slow down but atoms are connected red to blue which differs from solid and liquid.
4) To make oxygen become a liquid there has to be a temperature of 28 K and a pressure of 10-15 atm
5)
D 8.2 Use the major ideas of atomic theory and molecular theory to describe physical and chemical interactions among substances, including solids, liquids, and gases

During the simulation this standard was met easily. Taking different variables like amount of pressure and temperature the simulations tested interactions with solids, liquids and gases. The simulation showed how the three substances would react and different ways they could be manipulated.

D 8.4 While conducting investigations, use the science themes to develop explanations of physical and chemical interactions and energy exchanges.

This activity walks through the terms of chemical reactions. It talks about the different things that happen when a chemical reaction takes place. The simulations show how energy is exchanged causing the matter to change states.
