Molecules with stronger intermolecular force have higher freezing points. > Letâs look at it from the point of view of a solid, where the particles are held in position by their intermolecular forces of attraction. If we raise the temperature enough to overcome these forces, the solid will melt.
Although it is smaller than each of the Great LakesâOntario, Erie, Huron, Superior, and MichiganâLake Champlain is a large body of fresh water. Approximately 1,269 km2 (490 sq mi) in area, the lake is roughly 201 km (125 mi) long, and 23 km (14 mi) across at its widest point.
Several glacial lakes of varying elevation occupied the basin before the current level and outlet were established about 11 000 years ago. Lake Ontario is 19 000 km2 (10 000 km2 in Canada), with a drainage area of 90 130 km2, an elevation of 74 m, a mean depth of 86 m (max 244 m), length 311 km and width 85 km. It is the smallest in surface area and most easterly of the GREAT LAKES and eighth-largest body of fresh water in North America.
