FIRST EXAMINATION IN MEDICINE.

EXPERIMENTAL PHYSICS.

PROFESSOR BErgin.

1. Define osmotic pressure, and describe some method of measuring it. How has it been explained?

2. A flask of 200 c.c. capacity, filled with air at 100° C., is placed with its mouth under mercury; if it be allowed to cool to 10° C., calculate the weight of mercury which will flow into the flask.
