Matter and its properties

Matter

100

What is matter?

Matter is anything that has mass and occupies a space

200

What is the unit of volume in International System ?

Cubic metre- m³

300

What is the difference between a material object and a material system?

We can easily define the limits of a material object (like a rock), whereas we don't know the limits of a material system (like seawater).

400

What is the difference between quantitative and qualitative properties?

Quantitative- Properties of matter that can be measured.

Qualitative - Properties that help us describe the object but which can not be measured.

500

What is the difference between intensive and extensive properties?

Intensive properties- these do not depend on the amount of matter in the object.

Extensive properties- these depend on the amount of matter in the object.

Mass

100

What is 'Mass'?

Mass is the amount of matter that an object has.

200

What is the unit of mass in International System?

Kilograms (Kg)

300

How many grams are there in 25 kilograms?

25000 grams

400

How many Kilograms are there in 750 Decagrams?

7.5 Kilograms

500

Mass is an:

   a. Extensive and qualitative property of               matter

   b.Intensive and qualitative property of                matter.

   c.Extensive and quantitative property of              matter. 

   d.Intensive and qualitative property of                matter.

Volume and Capacity

100

What is the definition of volume?

Volume is the space occupied by an object.

200

What is the common unit of capacity?

Litre

300

What is the relation between litre and cubic centimetre? 

1litre = 1000 cm³

400

What is the relation between litre and cubic decimetre?

 1litre = 1 dm³

500

What is the expression to calculate the volume of a sphere?

V=4/3 π.r³

Density

100

 What is the definition of density?

The density of a substance is the relationship between its mass and volume,

Or, mass per unit volume.

200

What is the expression to calculate the density of the matter?

Density, d=m/V

300

What is the unit of density in International System?

kg/m³

400

What is the density of water?

1 g/cm³

500

Density is an:

a.Extensive and qualitative property of matter

b.Intensive and qualitative property of matter.

c.Extensive and quantitative property of matter. 

d.Intensive and quantitative property of matter. 

d.Intensive and quantitative property of matter.
