The diagram below shows two set-ups, X and Y, with different amount of water in each beaker. The beakers were placed above two Bunsen burners for 5 minutes. beaker X 100 ml of water 70+ 60- 50- 40+ Set-up X 0 The temperature of the water in the two beakers were recorded as shown in the graph below. Temperature (°C) plastic covers Bunsen- burners Set-up X: Line Set-up Y: Line_ Line P Line Q Set-up Y 5 beaker Y 200 ml of water Time (minutes) (a) Which line, P or Q, in the graph above represent the temperature of water in Set-up X and Set-up Y? [1] (b) Based on your answer in (a), explain the difference in the changes in the temperature shown in the graph up to the 5th min.
