1. Consider heating water to make a cup of coffee. Describe what happens to the submicroscopic particles that make up the water (focus on starting with cooler water and ending with very hot water, just prior to boiling)?

1. According to kinetic-molecular theory, all submicroscopic particles, even those of a solid, are always in motion. Solids SMPs vibrate, but are otherwise "locked" into place relative to other solid SMPs. When we hold a solid in our hand, can we directly feel the individual particles moving? How can we indirectly feel the particles moving when we hold a solid? As part of your explanation, imagine your are holding a hot penny in one hand and a cold penny in the other hand.

1. The figure below represents the moving particles of a gas within a rigid container. Each circle represents a single submicroscopic gas particle. Of course,real particles DO NOT have tails behind them. The tails are an attempt to indicate the relative motion of the particles. In the space to the right of the figure, redraw the diagram as it would appear after the container was heated. Briefly justify/explain your drawing.
