AP EAMCET · PHYSICS · Thermal Properties of Matter
Two metal plates and of same material are arranged as shown in the figure. If both the plates are uniformly heated through same range of temperature, then 
- A Both and increase
- B Both and decrease
- C decreases and increases
- D increases and decreases
Answer & Solution
Correct Answer
(C) decreases and increases
Step-by-step Solution
Detailed explanation
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.
