Duration: 30 min

Creator: Encyclopaedia Britannica Educational Corporation

Description: The pressure at 100° is read for a constant number of moles of gas at constant volume. The gas is then cooled to 27° C, and the pressure is read again. The gas is placed in an ice bath, and the pressure is read again. Points out that the best value from many accurate determinations is called absolute zero.
