Which of the following statements is correct
Correct answer: A. Hooke's law is applicable only within the elastic limit
- A. Hooke's law is applicable only within the elastic limit
- B. The adiabatic and isothermal elastic constants of a gas are equal
- C. Young's modulus is dimensionless
- D. Can't be predicted
Explanation
Option A is correct because Hooke's law is valid only within the elastic limit of a material, meaning the material will return to its original shape once the force is removed. Option B is incorrect because adiabatic and isothermal elastic constants differ due to different conditions of heat exchange. Option C is incorrect because Young's modulus is a measure of stiffness and has units of pressure (N/m²). Option D is incorrect as these properties can indeed be predicted based on physical principles.
