Two metal plates P and Q of same material are arranged as shown in the figure. If both the plates are uniformly heated through same range of temperature, then

  1. Both x and y increase
  2. Both x and y decrease
  3. x decreases and y increases
  4. x increases and y decreases

Solution

From the phenomenon of thermal expansion, plates $\mathrm{P}$ and $\mathrm{Q}$
are uniformly heated through the same range of temperature.
Thus, both the plates expand outwards.
Hence, both distance x and y decrease.
