A student carries out an experiment to find the relationship between the pressure p and the volume V of a fixed mass of gas. The table contains four of her sets of measurements. p / kPa V / cm3 30.0 15.2 9.8 7.6 Use the data in the table to suggest the relationship between the pressure and the volume in this experiment. Explain how you reach your conclusion. State the property of the gas, apart from the mass, that remains constant during the experiment. A lake is 5.0 m deep. The density of the water is 1000 kg / m3. Calculate the pressure at the bottom of the lake due to this depth of water. pressure = A bubble of gas escapes from the mud at the bottom of the lake and rises to the surface. Place one tick in each row of the table to indicate what happens to the volume, the mass and the density of the gas in the bubble. Assume that no gas or water vapour enters or leaves the bubble. increases stays the same decreases volume of bubble mass of gas in bubble density of gas in bubble
