Class 11

Under increasing load, the graphical representation showing the relationship between strain and stress for a given material is called the stress-strain curve. It provides the crucial information about the yield point (onset of payment deformation),  material's elastic limit, fracture point (point of breaking), and ultimate tensile strength (maximum stress the material can withstand). The toughness of the material is represented by the area under the curve.

Shear modulus (G) or rigidity modulus is the ratio of shearing stress to shearing strain within the elastic limit. It helps measure the solid's resistance to deformation by parallel forces acting tangentially on its surface. Mathematically,  
G= Shearing Strain/Shearing Stress = (F/A)/0
Where, A is the area on which the force acts, F is the tangential force and is the angle of shear.  

According to the class 11 mechanical properties of solids, Bulk modulus (K) is within the elastic limit, the ratio of volumetric stress to volumetric strain. Bulk modulus measures the resistance of a solid or fluid to compression. Mathematically, it is represented as the,
K= Volumetric Strain/Volumetric Stress = -P/ (? V/V0)
Where P is the pressure applied, V0 is the original volume, and? V is the change in volume. The negative sign means that volume decreases with increasing pressure.   

The questions and answers for Class 11 Chemistry Chapter 1 are provided in this article. However, students can also refer their textbooks for intext questions.

There are six chapters in class 11 Chemistry part 1.

Thermodynamics class 11 ncert solutions notes are used for revision and practice. Students can check their preparation level by solving the NCERT Class 11 Chemistry Chapter 6 Thermodynamics solutions pdf regularly.

Students must use Thermodynamics ncert pdf after completing their course. Directly solving the Class 11 Thermodynamics ncert solutions will create confusion.
