A student investigates the relationship between the temperature and pressure of a fixed volume of air using a brass bulb and an analogue pressure gauge.

They use the apparatus shown in the diagram below:

Diagram of the apparatus used to investigate how gas pressure varies with temperature. A brass bulb containing air is submerged in a beaker of water. The beaker sits on a tripod and gauze above a Bunsen burner. A liquid-in-glass thermometer is immersed in the water bath. A long, wide flexible plastic tube connects the top of the bulb to an analogue pressure gauge situated outside the beaker.

Suggest two ways the student could improve this investigation to obtain more accurate temperature and pressure measurements.
