A student stretches two different springs, Spring P and Spring Q, and measures their extensions under different constant forces. They plot their findings on the graph below:

Graph showing Force (N) on the vertical axis against Extension (cm) on the horizontal axis. The vertical y-axis ranges from 0 to 12 N with major grid lines every 2 N and minor grid lines every 0.2 N. The horizontal x-axis ranges from 0 to 10 cm with major grid lines every 2 cm and minor grid lines every 0.2 cm. Curve P is a straight, linear line from the origin (0,0) to (4.0 cm, 8.0 N), after which it curves and flattens, ending at approximately (8.0 cm, 9.8 N). Curve Q is a straight, linear line from the origin (0,0) to (6.0 cm, 6.0 N), after which it curves and flattens, ending at approximately (10.0 cm, 7.5 N)..

Describe and explain the behaviour of Spring P and Spring Q. Use data from the graph and calculations in your answer.
