Chemistry Chapter 6 :Air and atmosphere

ANS IN DETAIL ÷

 A.1. The following facts show that air is a mixture ÷

1 The composition of air is not constant it varies from place to place from time to time.

2 The component of air retain their identity.

3 The properties of air represent the average of the properties of its Component gases.

4 The component of air can be readily separated by simple physical methods.

 

A2 .1 Take a glass breaker filled with ice cubes and leave it in air for sometime. 

2 Water droplets will appear on the outer surface of the breaker.

3 This is due to the condensation of the water vapour.

4 This this show that air contains water .

 

A.3 The harmful effects of air pollution are ÷

1 Excess of carbon dioxide caused suffocation. 

2 Carbon monoxide the deadly poisonous gas released from automobiles reduces oxygen carrying capacity of blood. 

3 Sulphur dioxide released from coal and oil combustion headache, constriction, irritation in the respiratory tract and vomiting. 

4 Nitrogen oxides released from automobiles affect the respiratory system of animals 

 

A.4. Bring a matchstick near the has evolving if matchstick start burning fastly than the gas evolved will be oxygen as it increase the rate of burning.

 

A.5 Proteins are essential for growth and development of plants nitrogen helps in building the proteins in the plant by the nitrogen fixing bacteria .

 

A.6 It prevent all the heat from the sun reaching to the earth it helps in maintaining the water cycle ,helps in moderating temperature on the surface of the earth.

 THINK CRITICALLY

A.1 The following prove that air is a mixture:

1. The composition of air is not constant it varies place to place to place and time to time .

2. The different components of air retain their identity.

3 The properties of air represent the average of thier properties  of its component gases.

4 The component of air can be readily separated by simple physical methods .

Take a burning candle and put it near the hole of cardboard A. Try to see the burning candle through the hole of cardboard C. You will be able to see the burning candle. Now place the cardboard B in such a way that all cardboards are not in the straight line. Now again try to see the candle light, this time you will not be able to see the candle light. This activity shows that light travels in a straight line.

Dig.:

 

9. Ans: Working of a pinhole camera

Place a luminous object such as a burning wick (XY) of the candle in      front of the pinhole, an inverted picture X’Y’ of the wick is obtained on the wax paper. This picture is called the image.

The image obtained is inverted.

Such an image is formed because the light travels in a straight path. Hence, light from the upper point X of the wick passes through the pinhole and strikes the wax paper at X’.
Similarly, light from the lower point Y of the wick passes through the pinhole and strikes the wax paper (or screen) at Y'.

When light from all other points between X and Y passes through the pinhole they strike the wax between X' and Y'. Hence, an inverted image is formed on the wax paper.

10. Ans: Diagram from the book. 

11. Ans: Diagrams from the book.

12. Ans: Lunar eclipse occur when earth comes in between the sun and the moon. The shadow of earth falls on the moon. Lunar eclipse can full or partial.

f.        What is a language processor?

Ans. A language processor is a software that converts source program into machine language because a computer does not understand the program written in HLL or assembly language.  

6.     Answer Briefly.

a.      How will you classify programming languages?

Ans. Programming languages are classified into two major categories:

1.      Low Level Language (LLL)

(i)                  Machine Language         (ii)        Assembly Language

2.      High Level Language (HLL)

(i)                  Procedural Language     (ii)  Non-procedural     (iii)   Natural Language

 

b.      Differentiate between Procedural and Non-procedural programming languages.

Ans. Procedural Language- A procedural language is also called a third-generation language (3GL). In this language, the Programmer writes instructions that tell the computer what to do and how to do it.

Non-procedural language- A non-procedural language is also called a fourth-generation language (4GL). In this language, the programmer only specifies what the program should do without explaining how.

c.       How is Machine Language different from Assembly Language?

Ans.  Machine Language- A machine language, also called first-generation language, is a language directly understood by a computer without any translation. It refers to 0s and 1s that a computer can understand as instructions.

Assembly Language- Assembly language, also called second-generation language, is also a low-level programming language. A program written in assembly language uses short sequence of letters called Mnemonic codes such as ADD for addition, MUL for multiplying.

d.      Differentiate between compiler and interpreter.

Ans. Compiler- A compiler converts HLL program into machine language. It converts the entire HLL program into machine language.

Interpreter- Interpreter also converts HLL into machine language. It converts one line of program at a time. It displays the error one line at a time and goes to the next line only after correction of that error.
