Al-Huda Science Academy is focusing not only on short questions and long questions but also on MCQs of Chapter 4 Chemistry Class 11. Entry Tests required a lot of effort on Multiple Choice Questions that should be of conceptual in nature. The users can participate without login to MCQs test. All MCQs are taken from the past papers of Punjab Boards including Bahawalpur Board, DG Khan Board, Faisalabad Board, Gujranwala Board, Lahore Board, Multan Board, Rawalpindi Board, Sahiwal Board and Sargodha Board. Chapter 4 of F.Sc Part 1 Chemistry is based on Liquids and Solids. In this chapter, students will learn about concepts of:

Liquids and Solids Laws and Applications.
