Young's modulus is the property of __________?
Correct answer: C. Solid only
- A. Gas only
- B. Liquid only
- C. Solid only
- D. All of the above
Explanation
Young's modulus is the ratio of tensile or compressive stress to the corresponding strain, and it describes the elastic deformation of solids. Liquids and gases do not sustain a static tensile or compressive shape in the same way, so this modulus is ordinarily assigned to solids. Students may choose all of the above by treating every material's resistance to deformation as Young's modulus.

About Resistance and Resistivity
Resistance measures opposition to current in a conductor and follows R = V/I for an ohmic conductor, while resistivity is an intrinsic property of the material. Questions use R = ρL/A, examine effects of length, cross-sectional area and temperature, and distinguish resistance, resistivity, conductance and conductivity.
