Heating a volume of air can lead to both an increase in volume
and an increase in pressure. In this experiment the
volume must be kept constant. This is achieved by marking the
initial water level in limb a of the manometer and resetting the
water level to this mark before reading the new pressure.
In a supplementary problem the temperature-pressure coefficient is
calculated and compared with the reciprocal of the absolute
temperature.
How does the pressure of a volume of air change during heating?
Measure the pressure change in a specific volume of air during
heating at constant volume.
