The value of coeffecient of expantion of material depends upon

Options

A. Length
B. Area
C. Temperature
D. Volume

Answer

To solve the question regarding the factors that affect the coefficient of expansion of a material, we can follow these steps:

### Step 1: Understand the Coefficient of Expansion
The coefficient of expansion (α) is a measure of how much a material expands per unit length, area, or volume when the temperature changes. It can be categorized into:
- Linear expansion (α)
- Areal expansion (β)
- Volumetric expansion (γ)

### Step 2: Identify the Factors Affecting the Coefficient of Expansion
The coefficient of expansion is primarily dependent on the properties of the material itself. This includes factors such as:
- Atomic structure
- Bonding forces
- Material composition

### Step 3: Analyze the Given Options
The question may provide options related to:
- Length
- Area
- Volume
- Temperature

### Step 4: Determine the Correct Answer
1. **Length, Area, and Volume**: The coefficient of expansion does not depend on the dimensions (length, area, or volume) of the material. For example, a short wire and a long wire made of the same material will have the same coefficient of expansion.

2. **Temperature**: The properties of materials, including the coefficient of expansion, can change with temperature. Therefore, the coefficient of expansion can vary with temperature changes.

### Conclusion
The correct answer to the question is that the coefficient of expansion of a material depends on **temperature**.

### Final Answer
The value of the coefficient of expansion of a material depends upon **temperature**.
