Question

Mention three factors on which superficial expansion depends on. Write the relationship between a, ß and V.

Answer 1

Answer:

Thermal Expansion

If the temperature increases, then the volume of the material also increases. Generally, this is known as thermal expansion. We can express it in this way that it is the fractional change in length or volume per unit change in temperature. In case of expansion of a solid, normally linear expansion coefficient is usually employed.

In case of thermal expansion of solid, it is described in terms of change in length, height, and thickness. For liquid and gas, the volume expansion coefficient is more useful. Generally, if the material is a fluid then we can describe it in terms of change in volume.

Explanation:

Answer 2

• The amount by which it expands depends on three factors: its original length, the temperature change, and the thermal (heat) properties of the metal itself. Some substances simply expand more easily than others.
