Maria places a beaker of 20°C water on a burner and heats the water until it reaches 100°C. She measures the temperature and the mass of the beaker of water every minute for 12 minutes. The graph shows some of her results.
The image shows a 2-dimensional graph named as Water Temperature has Time in minutes on x-axis and Temperature of water in (c) on y-axis. A curve is drawn passing through points (0,20), (3,55), (4.5,80) and (11,100).
Select the graph that most likely shows Maria’s data for the mass of the beaker of water.
A. The image shows a 2-dimensional graph named as Mass of Water has Time in minutes on x-axis and Mass of water in grams on y-axis. A curve is drawn passing through points (0,200), (5,800), (8,1000) and (12,1000).
B. The image shows a 2-dimensional graph named as Mass of Water has Time in minutes on x-axis and Mass of water in grams on y-axis. A line is shown passing through points (0,900) and (11,100).
C. The image shows a 2-dimensional graph named as Mass of Water has Time in minutes on x-axis and Mass of water in grams on y-axis. A curve is shown passing through points (0,400), (6,700) and (12,400).
D. The image shows a 2-dimensional graph named as Mass of Water has Time in minutes on x-axis and Mass of water in grams on y-axis. A curve is shown passing through points (0,500), (6,500) and (12,450).
