Ritu took two bimetallic strips, I and II (of equal size, length and breadth) made up of metals P and Q; and Q and R, respectively as shown here.
She subjected each bimetallic strip to heating for
same time period. The given diagram shows her
experiment.
Which of the following cannot be inferred from the
above experiment?
AMetal P expands more as compared to metals
Q and R on heating for the same time period.
BMetal R contracts more as compared to metals
P and Q on heating for the same time period.
CThe ascending order of expansion of these metals
when subjected to heating is R < Q < P.
DBoth B and C
