Question

State whether the following statements are True
or False. Correct the false statements
1.Relative density of water is 1300 kg/m
2 Density of aluminium block and rod is not the same
3. Density is a measurable physical quantity
4. Density of a substance increases with temperature
5. If density of an object is more than 1 g/cm. then it will float in water.​

Answer 1

Explanation:

1. 1000 kg/m³ (false)

2. true

3.true

4. false

5. true

Answer 2

Answer:

1) False

 The density of water is 1000kg/m³

 Relative density = 1000/1000 = 1

2) False

  The density of a given material is constant regardless of the shape of the        

  object

3) True

4) False

   On increasing the temperature, the distance between the molecules

   increases slightly thus increasing volume and hence decreasing density

5) False

   For an object to float on water, its density must be less than water. The

   density of water is 1g/cm³.
