Water
Activity 1.7
Take a plastic mug. Drill two holes at its
base and fit rubber stoppers in these holes.
Oxygen
Insert carbon electrodes in these rubber
stoppers as shown in Fig. 1.6.
Test tube
Connect these electrodes to a 6 volt
battery
Graphite rod
Fill the mug with water such that the
electrodes are immersed. Add a few drops
of dilute sulphuric acid to the water.
Take two test tubes filled with water and
Anode
invert them over the two carbon electrodes.
Switch on the current and leave the

apparatus undisturbed for some time.
You will observe the formation of bubbles
at both the electrodes. These bubbles displace water in the

test tubes.
Is the volume of the gas collected the same in both the test tubes?
Once the test tubes are filled with the respective gases, remove
them carefully.
- Test these gases one by one by bringing a burning candle close
to the mouth of the test tubes.
CAUTION: This step must be performed carefully by the teacher.
What happens in each case?
Which gas is present in each test tube?​

Answer 1

Answer:

Electromagnetic energy traveling through a vacuum behaves in some ways like Ocean waves travelling through water like Ocean waves electronic energy is character style characterized by wavelength and frequency
