Fsc 1st Year Physics Chapter 11(Optical Instruments) Short Questions with Answers Online Preparation

Physics is one of the most tricky and hardliner subject like Maths but if deals carefully, it can grant high scores on result board. Well, as we all know that Short Questions have their own importance in not only in Physics but in all other subjects, which unfortunately undermined due to the extra burden of long questions. Therefore, mostly students don't know how to deal with the objective part and trust me, it really needs attention.

Ok! Don't worry, I know you don't have much time to spend extra time on short questions, therefore, here I am going to introduce you the best platform for your all academic solutions. Yes, I am talking about ilmkidunya.

As, FSC part-1 is the most decisive period of a student's life, therefore ilmkidunya gives much importance to the preparation of FSC exams and helps students with multiple ways.

Well! praise to ilmkidunya, who brings you not only such guidance and online test system for Physics but also notes and online preparations, through which you can learn a lot while sitting at home.

Lets discuss here about the short questions of, one of the most interesting Chapter of FSC part-1 Physics book. Chapter 11 is termed as “Heat and Thermodynamics”.

After reading this chapter students will be able to learn about:

Kinetic theory of gasses.

Gas laws on the basis of K8netic theory.

Concept of reversible and irreversible process.

Defining heat engine.

Carnot theorem and to describe it.

So, dear readers, hope you are satisfied and well aware of where to come for the best short questions preparation. Yes! It is ilmkidunya. Where you find each and everything related to your exams and study guidance. Past Papers, which are not an easy task to get but at ilmkidunya you can find all at one place, because it is not just a forum for the help of some specific students but for all.

Question # 1

Why we reduce pressure in the tyre while moving on motorway?

Ans 1: We reduce the pressure in the tyre while moving on motorway because when a car is driven through some distance,its tyres become hot due to work done against friction between the tyres and the road which appears as heat. This heat is absorbed by the gas molecules contained in the tyre which results in an increase in pressure of the gas. If the pressure in the tyre is not reduced then the tyre may burst.

Question # 1

Does entropy of a system increase or decrease due to friction?

Ans 1: The entropy of a system increase due to the friction as work done against friction is changed into heat and heat added to the system increase its entropy.
