NCERT Class 8 Science Chapter 7 Particulate Nature of Matter Test Mock Test
This free online test covers Chapter 7, Particulate Nature of Matter, from the NCERT Class 8 Curiosity textbook. The 29 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.In Activity 7.1, a stick of chalk is broken and then ground into a fine powder. The chapter classifies this as:
- AA physical change, because the chalk does not turn into a new substance and only the size of each speck is reduced
- BA chemical change, because the chalk cannot be put back together
- CA chemical change, because a new substance is formed on grinding
- DNeither a physical nor a chemical change, since nothing about the chalk alters
Q2.The chapter defines a constituent particle as:
- AThe basic unit that makes up a larger piece of a substance or material

- CA tiny dust particle suspended in the air
- DAny small grain of a substance that can still be seen with a magnifying glass

- ASugar has been destroyed and only its taste remains
- BSugar changes into a new substance that only exists in the top layer
- CSugar breaks up into constituent particles that spread through the water, though they can no longer be seen
- DSugar particles float to the top because they are lighter than water
