Question

A metallic wire is stretched in such a way that its new length becomes twice the original length. How does its specific heat capacity change?

पर्याय

• becomes double

• becomes 4 times

• becomes 1/4

• remains the same

Answer 1

remains the same

Explanation:

Specific heat capacity is a property of the material and does not depend on the shape, length or size of the object. When the metallic wire is stretched so that its length becomes twice the original length, only its dimensions change, while the material remains the same.

Therefore, the specific heat capacity remains unchanged.
