Multiple Choice

Assuming that all other factors are equal,on a cold winter afternoon the amount of dissolved O₂in a lake will be

A) more than on a hot day because the decreased energy in colder water makes O₂molecules less likely to escape to the atmosphere,and biological oxygen demand will be higher than on a hot day.
B) less than on a hot day because the decreased energy in colder water makes O₂molecules more likely to escape to the atmosphere,and biological oxygen demand will be higher than on a hot day.
C) more than on a hot day because the decreased energy in colder water makes O₂molecules less likely to escape to the atmosphere,and biological oxygen demand will be lower than on a hot day.
