Q. In linear expansion, the increase in length is proportional to __________.

रैखिक विस्तार में, लंबाई में वृद्धि __________ के समानुपाती होती है।

A
Temperature only
केवल तापमान
B
Original length only
केवल मूल लंबाई
C
Both original length and temperature change
मूल लंबाई और तापमान दोनों में परिवर्तन होता है
D
Final temperature only
केवल अंतिम तापमान

Explanation

Linear expansion of a solid is described by the formula:
ΔL=αLΔT\Delta L = \alpha L \Delta T
This equation shows that the change in length (ΔL) is directly proportional to both the original length (L) and the temperature change (ΔT). So, doubling either L or ΔT will double ΔL.
