Fig 4 1 shows a Galilean thermometer This thermometer is used to measure the approximate temperature of the surrounding air glass cylinder water entia bulb E label 28 C bulb D label 26 C bulb C label 24 C bulb B label 22 C bulb A label 20 C Fig 4 1 The glass cylinder contains water When the temperature of the water changes so does its density Each bulb has a label printed with a temperature as shown in Fig 4 1 The bulbs have different densities At 21 C only bulb A is at the bottom of the cylinder a Explain in terms of density why bulb A is at the bottom of the cylinder and the other bulbs are floating
