SUBHANI · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [A]
## CONCEPT FRAMEWORK
	**Primary Concept**: Bulk Modulus
	**Related Topics**: Stress, Strain, Elasticity
	**Prerequisites**: Understanding of material properties and mechanical deformation.
## SOLUTION PATHWAY
**Given Information**:
	No numerical information is given. 
	The question asks for the definition of bulk modulus.
**Method & Steps**:
	1. **Definition of Bulk Modulus**: The bulk modulus (K) is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease in volume. It describes a material's resistance to uniform compression.
		Reasoning: This is a fundamental definition in material science.
		Formula/Rule:  $K = -V \frac{dP}{dV}$, where $K$ is the bulk modulus, $V$ is volume, and $P$ is pressure.
	2. **Interpretation**: The higher the bulk modulus, the more resistant a material is to compression.
		Working: This means a large change in pressure is required to cause a small change in volume.
	3. **Conclusion**: Therefore, bulk modulus measures resistance to uniform compression.
		Result: The correct answer is the option that states resistance to uniform compression.
 ## OPTION ANALYSIS
[A] ✓:  The bulk modulus specifically quantifies a material's resistance to uniform compression, meaning how much pressure it can withstand before a significant volume change occurs. This is the correct definition.
[B] :x: Resistance to stretching is measured by Young's modulus, not the bulk modulus.
[C] :x: Resistance to bending is related to flexural modulus or bending stiffness, not the bulk modulus.
[D] :x: Resistance to shearing is measured by the shear modulus, not the bulk modulus.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. [Confusing with other moduli]: Mixing up bulk modulus with Young's modulus or shear modulus. Remember each modulus measures resistance to different types of deformation.
		2. [Not understanding compression]: Forgetting that bulk modulus is specifically related to volumetric changes due to pressure.
	**Quick Tips**:
		1. [Remember 'bulk']: Think of 'bulk' as referring to the whole volume, which is affected by compression.
		2. [Relate to pressure]: Think of the bulk modulus as how much pressure it takes to compress a material a certain amount.
