PURPOSE: To demonstrate heat capacity.
DESCRIPTION: Equal volume balls made of different materials are placed on a plate of paraffin, as shown. The balls are warmed to the same temperature by boiling them in water. They melt down in the paraffin to different depths proportional to thier heat capacity.
EQUIPMENT: Paraffin pan and balls, as photographed. Also beaker with watr on a hot plate.
SETUP NOTES: 1/2 hour.
