Question

3. How will you measure the volume of a stone?
4. The mass of an iron rod is 52 g. The density of iron is 7.8 g em! Fi
5. Describe the method in steps to find the density of a pebble.
6. Acar covers 80 km in 2 hours and a bus covers 100 km in 5 hours.
OBSERVE AND PERFORM
A. Collect various stones, pebbles, coins and marbles of various shapes a
using the displacement method. Note your observations in the noteb
B. Collect various types of leaves from the garden. Measure their area us
occupies the largest area. Write your observations in the notebook.

Answer 1

Answer:

3. By using liquid displacement method since stone is an irregular object.

4. Volume of iron rod = mass / density = 52 g / 7.8 g cm^(-3)

= 6.67 cm^(-3)

5. You must first find mass of that pebble and it's density by using liquid displacement method. Then you must use density = mass / volume formula.

6. In complete question so no answer available.

For OBSERVE AND PERFORM, it's not possible to show theoretically
