X. Answer In detail.

Question 1.
Describe the graphical method to find the area of an irregularly shaped plane figure.
Answer:
To find the area of an irregularly shaped plane figure, we have to use graph paper.

  1. Place a piece of paper with an irregular shape on a graph paper and draw its outline.
  2. To find the area enclosed by the outline, count the number of squares inside it (M).
  3. You will find that some squares lie partially inside the outline.
  4. Count a square only if half (p) or more of it (N) lies inside the outline.
  5. Finally count the number of squares, that are less than half. Let it be

For the shape in figure we have the following:
M = 50
N = 7
P = 4
Q = 4
Now, the approximate area of the can be calculated using the following formula.

Area of the leaf = M+(34) N + (12) P+14 Qsq.cm
= 52 + 5.25 = 58.25 sq.mm = 0.5825 sq.cm

Question 2.
How will you determine the density of a stone using a measuring jar?
Answer:
Determination of density of a stone using a measuring cylinder.

  1. In order to determine the density of a solid, we must know the mass and volume of the stone.
  2. The mass of the stone is determined by a physical balance very accurately. Let it be ‘m’ grams.
  3. In order to find the volume, take a measuring cylinder and pour in it some water.
  4. Record the volume of water from the graduations marked on measuring cylinder. Let it be 40 cm3.
  5. Now tie the given stone to a fine thread and lower it gently in the measuring cylinder, such that it is completely immersed in water.
  6. Record the new level of water. Let it be 60 cm3

∴Volume of the solid = (60-40) cm3
= 20 cm3 = V cm3 (assume)
Knowing the mass and the volume of the stone, the density can be calculate by the formula:

XI. Questions based on Higher er Thinking skills:

Question 1.
There are three spheres A, B, C as shown below :
Answer:

Sphere A and B are made of the same material. Sphere C is made of a different material. Spheres A and C have equal radii. The radius of sphere B is half that of A. Density of A is double that of C.

Question 2.
Now answer the following questions:

  1. Find the ratio of masses of spheres A and B.
  2. Find the ratio of volumes of spheres A and B.
  3. Find the ratio of masses of spheres A and C.

Answer:
i. Ratio of masses of spheres A and B
MA : MB
D × VA : D × VB
Let the mass of sphere A = MA
Let the mass of sphere B = MB
Mass = Density × Volume
MA = DA × VA
MB = DB × VB (Density is same)
Volume of Sphere A =43πr3

ii. Ratio of volumes of spheres A and B
V: VB
8 : 1 (As mass is directly proportional to volume)

iii. Ratio of masses of spheres A and C.

[∴ Density of A is double that of C ]

XII. Numerical problems:

Question 1.
A circular disc has a radius 10 cm. Find the area of the disc in m2. (Use n = 3.14)
Answer:
Given radius = 10 cm = 0.1m
π= 3.14
Area of a circular disc A = ?
Formula : Area of a circle A = πr2
= 3.14 × 0.1 × 0.1
Solution : A = 0.0314 m2

Question 2.
The dimension of a school playground is 800 m x 500 m. Find the area of the ground.
Answer:
Given :The dimension of a school
Playground = l x b = 800 m x 500 m

Formula :Area of the ground A = l x b
= 800 x 500 = 4,00,000
A = 4,00,000 m2

Question 3.
Two spheres of same size are made from copper and iron respectively. Find the ratio between their masses. Density of copper 8,900 kg/m and iron 7,800 kg/m3
Answer:
Given : Density Copper Dc = 8900 kg/m3
Density of Iron D1 = 7800 kg/m3
Volume of Copper sphere = Volume of Iron sphere
To find : Ratio of Masses of Copper (MC) and Iron (MI)
Solution: Mass = Density x Volume
MC = DC x V, M1 = D1 x V
MC = 8900 V, M1 = 7,800 V
MC = M1
8900 V : 7800 V
= 1.14: 1

Question 4.

Answer:
Given : Mass of a liquid M = 250 g
Volume V = l000cc

Solution: Density of the liquid = 0.25 g/cc

Question 5.
A sphere of radius 1cm is made from silver. If the mass of the sphere is 33 g, find the density of silver (Take π = 3.14)
Answer:
Given : radius of a sphere r = 1cm

VIII. Long Answer

Question 1.
How will you find the volume of an irregularly shaped object (stone) by using measuring cylinder?
Answer:

  1. Take a measuring cylinder and pour some water into it.
  2. Note down the volume of water from the readings of the measuring cylinder.
  3. Take it as V1
  4. Now take Q small stone and tie it with a thread.
  5. Immerse the stone inside the water by holding the thread.
  6. This has to be done such that the stone does not touch the walls of the measuring cylinder.
  7. Now the level of water has raised.
  8. Note down the volume of water and take it to be V2

The volume of the stone is equal to the raise in the volume of water.
V1 = 30cc, V2 = 40cc
Volume of stone = V2 – Vj = 40 – 30 = 10cc

IX. Problems for practice:

Question 1.
A piece of iron weighs 230 g and has a volume of 20 cm3. Find the density of iron.
Solution:
Mass of iron (m) = 230 g
Volume of iron (v) = 20 cm3

Question 2.
Find the mass of silver of volume 50 cmand density 10.5 g / cm3
Solution:
Mass of silver (M) = ?
Volume of silver (V) =50 cm3
Density of silver D = 10.5 g/cm3

mass (M) = Density × Volume
= 10.5 x 50 = 525 g

X. Creative questions: HOTS

Question 1.
Why does an iron needle sink in water, but not an iron ship?
Answer:
Iron needle is compact and its density is 7.6 g/cm3 Thus, as the density of iron needle is more than 1 g/cm3 therefore, it sinks in water. However, the iron ship is constructed in such a way that it is mostly hollow from within, thus, the volume of iron ship becomes very large as compared to its mass and hence its density is less than lg/cm3 . As the density of iron ship is less than 1g/cm3, therefore it floats in water.
