Question

two identical copper rods one hollow and other solid are heated to the same rise in temperature will the two rods expand equal or unequally .Also give reason

Answer 1

the two rods will expand equally. because deformation coefficient of both the cu rod is same

Answer 2

Answer:

When two identical copper rods are heated to the same rise of temperature, both the solid and hollow rod will expand equally.

Explanation:

When the rods are heated they undergo thermal expansion.

Thermal expansion is the tendency of matter or material to change its shape, volume, and area when there is a change in temperature.

The factors on which the thermal expansion depends are:

• Length of the rods
• Rise in temperature
• Nature of the material

Now, the one hollow rod and the solid rod are identical in length and the rise in temperature for both the rods is equal, and made of the same material which is copper.

Therefore, the solid and the hollow rod will expand equally.
