NAME __________________ CLASSIX SEC:____________

1. Demonstration based worksheet-(5)

2.MCQ’s-(3)

3.Comprehension passage- (2)(Do Any One)

I. Demonstration of activity 1.4 on page 2, of class IX NCERT textbook. For better observation, crystals of KMnO4 in the place is taken in place of honey.

Q1. What change is observed in the two beakers? ______________________________________________________________________________ ______________________________________________________________________________ _____________________________________________________________________________

_ Q2. In which beaker has the change occurred more quickly? ______________________________________________________________________________ _____________________________________________________________________________

_ Q3. Name the process involved in the observed change. ______________________________________________________________________________ ______________________________________________________________________________

Q4. Why is the time taken for the change to occur different in the two beakers? ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________

Q5. Give an example of such a change from your daily life

II.Choose the best correct option in the following questions :

Q.1. Which of the following changes represent sublimation?

(a) solid liquid (b) solid gas (c) liquid gas (d) gas liquid

Q.2. Gases do not have–

(a) high compressibility (b) high fluidity (c) high density (d) large volume

Q.3. When describing the color, size, shape, or smell of an object, you are describing the

a. properties of matter b. states of matter c. volume of matter d. mass of matter

Q.4. Particles of a liquid–

(a) are most ordered (b) move randomly

Q.5. Which of the following pairs will not exhibit diffusion?

(a) hydrogen, oxygen (b) oxygen, water

Q.6. Which of the following is not a property of solids

(a) fixed shape and volume (b) interparticle spaces are minimum

(d) Forces of attraction between the particles are maximum

III.CAN PARTICLES IN MATTER MOVE?

Particles are different in different states of matter. The particles in liquids are much farther apart than particles in solids. Particles in solids pull toward each other. A solid can keep its shape because its particles stay close together. Particles in solids can move back and forth but they can’t change places with another particle. Particles in liquids are farther apart. The pull between particles in liquids is weaker than the pull in solids. Liquids can change shapes because the particles can move around each other and change places. Particles in gases do not pull together strongly. Gas particles can move around more than the particles in liquids and solids. A gas can move to fill any space because its particles move freely.

ANSWER THE QUESTIONS:

1. Are particles in all forms of matter the same? Yes No

2. How are the particles in liquids different from the particles in solids?

3. Why can gas fill any space?

4. Compare the properties of matter based on (shape and volume, space between the particles, force of attraction)

IV. WHAT MAKES UP MATTER?

Matter is made up of tiny particles. These particles are called atoms. Atoms are the smallest unit of matter. You can’t see atoms because they are so tiny. Two or more atoms can join together to make larger particles of matter. These larger particles can join other particles to make up the matter you can see. Atoms join together to make up different kinds of matter. Oxygen is made up of just one kind of atom. Water has two atoms that join together to make water. ANSWER THE QUESTIONS: 1. What is an atom?

2. Why can’t you see an atom?

3. How many kinds of atoms does water have?

4. How many kinds of atoms does oxygen have?
