Review test of 'States of matter' lesson in Chapter 'Matter in our surroundings' os class IX cbse doesnot correspond to the syllabus. The standard is way above what is taught in the lesson. Please change the review test to reflect the correct syllabus.
The review test does not contain any such problem. All the questions are from syllabus only. However, standard of question is a bit higher so as to built the knowledge and thinking ability of a student.
