Top Properties of Matter Questions for NEET

The Top 5 Properties of Matter Questions are extremely important for NEET Physics because this chapter is directly formula-based and frequently asked in numerical form. Questions from elasticity, surface tension, viscosity, and fluid mechanics appear regularly, making the Properties of Matter Questions a high-scoring and predictable section.

Understanding the Properties of Matter Questions ensures clarity in concepts like stress-strain relations, fluid flow, capillarity, and terminal velocity, all of which are commonly tested in NEET. This article provides detailed explanations of the Properties of Matter Questions along with additional practice questions to strengthen your preparation.

Question 1: Stress-Strain Relation and Young’s Modulus

One of the most important Properties of Matter Questions is based on elasticity and Young’s modulus.

Stress is defined as force per unit area:$$\text{Stress} = \frac{F}{A}$$Stress=AF​

Strain is defined as change in length per original length:$$\text{Strain} = \frac{\Delta L}{L}$$Strain=LΔL​

Young’s modulus is given by:$$Y = \frac{\text{Stress}}{\text{Strain}} = \frac{FL}{A \Delta L}$$Y=StrainStress​=AΔLFL​

This relation is fundamental in solving numerical problems. In NEET, questions often involve comparing elongation in different wires or finding extension under applied force.

The key takeaway from this Top 5 Properties of Matter Questions concept is that a higher Young’s modulus means the material is more rigid and less elastic deformation occurs.

Question 2: Energy Stored in a Stretched Wire

This is a very commonly asked numerical from the Top 5 Properties of Matter Questions.

The work done in stretching a wire is stored as elastic potential energy:$$U = \frac{1}{2} \times \text{Stress} \times \text{Strain} \times \text{Volume}$$U=21​×Stress×Strain×Volume

Alternatively:$$U = \frac{1}{2} F \Delta L$$U=21​FΔL

This concept is important because NEET often asks about energy stored when force is applied gradually. Students must remember the factor of $\frac{1}{2}$21​, as missing it leads to incorrect answers.

This makes it one of the most scoring numerical concepts within the Top 5 Properties of Matter Questions.

Question 3: Surface Tension and Capillarity

Surface tension is another frequently tested concept in the Top 5 Properties of Matter Questions.

The height of liquid rise in a capillary tube is given by:$$h = \frac{2T \cos \theta}{\rho g r}$$h=ρgr2Tcosθ​

Where:

• $T$T = surface tension
• $r$r = radius of tube

This formula shows that height is inversely proportional to radius, meaning thinner tubes result in higher rise.

In NEET, questions are often framed by changing radius or comparing two liquids. A key conceptual understanding is that surface tension arises due to cohesive forces between molecules.

This makes capillarity one of the most important applications in the Top 5 Properties of Matter Questions.

Question 4: Viscosity and Stokes’ Law

Viscosity deals with resistance to flow and is a major part of the Top 5 Properties of Matter Questions.

According to Stokes’ law, the viscous force acting on a spherical body is:$$F = 6 \pi \eta r v$$F=6πηrv

Where:

• $\eta$η = coefficient of viscosity
• $r$r = radius
• $v$v = velocity

Terminal velocity is given by:$$v = \frac{2r^2 (\rho – \sigma) g}{9 \eta}$$v=9η2r2(ρ−σ)g​

This concept is very important because NEET frequently asks about factors affecting terminal velocity. Increasing radius increases terminal velocity, while higher viscosity decreases it.

Understanding these dependencies is crucial when solving Top 5 Properties of Matter Questions.

Question 5: Bernoulli’s Principle

Bernoulli’s theorem is one of the most conceptual and application-based topics in the Top 5 Properties of Matter Questions.$$P + \frac{1}{2} \rho v^2 + \rho gh = \text{constant}$$P+21​ρv2+ρgh=constant

This equation represents conservation of energy in fluid flow.

Key insights include:

• Higher velocity → lower pressure
• Used in airplane lift, atomizers, and venturimeters

In NEET, conceptual questions are often asked based on pressure differences in moving fluids. Understanding real-life applications helps in solving these questions quickly.

This completes the core Top 5 Properties of Matter Questions.

Additional Practice Questions (Concept-Based)

To strengthen your understanding of the Top 5 Properties of Matter Questions, here are 10 additional questions:

If stress is doubled and strain remains constant, Young’s modulus doubles.

Energy stored in a stretched wire increases with extension.

Surface tension decreases with increase in temperature.

Capillary rise is inversely proportional to radius.

Viscosity is higher in liquids than in gases.

Terminal velocity increases with radius of the sphere.

Pressure in a fluid decreases as velocity increases.

Elastic limit defines maximum reversible deformation.

Bulk modulus measures resistance to volume change.

Poisson’s ratio relates lateral strain to longitudinal strain.

Key Formula Revision

For mastering the Top 5 Properties of Matter Questions, remember these formulas:$$Y = \frac{FL}{A \Delta L}$$Y=AΔLFL​ $$U = \frac{1}{2} F \Delta L$$U=21​FΔL $$h = \frac{2T \cos \theta}{\rho g r}$$h=ρgr2Tcosθ​ $$F = 6 \pi \eta r v$$F=6πηrv $$P + \frac{1}{2} \rho v^2 + \rho gh = constant$$P+21​ρv2+ρgh=constant

These formulas are repeatedly used in NEET and form the foundation of the Top 5 Properties of Matter Questions.

Common Mistakes Students Make

While solving the Top 5 Properties of Matter Questions, students often forget unit consistency, especially in viscosity and surface tension problems. Another common mistake is ignoring proportional relationships, such as capillary rise and radius.

Misapplying Bernoulli’s equation without considering height differences is also a frequent error. Avoiding these mistakes can significantly improve accuracy.
