Two systems are set up with semipermeable membranes separating solutions of unequal concentrations of NaCl. Each system has one solution that is 1.0 M and another solution that is 0.010 mM. They differ, however, in the temperatures at which they are maintained. One is held at 2°C and the other is held at 85°C. Which has the larger osmotic pressure?
a. The osmotic pressures are the same.
b. The hot system has the higher osmotic pressure.
c. The cold system has the higher osmotic pressure.
d. No osmotic pressure exists in either system.
