1. Calcination is a pyrochemical process in
which the ore is heated in the absence of
air.
2. It is a decomposition reaction.
3. It doesn’t require oxygen.
4. It is suitable to carbonate ores.
5. Ex : CaCO3 → CaO + CO2
12) Headlights of a car are connected in parallel.
In parallel connection, each headlight is exposed to the full potential difference supplied by the car’s electrical system, giving maximum brightness. Another advantage is that if one headlight burns out, the other one keeps shining.

13) A) Silver
b) Nichrome
14) (a) Ohm’s law: The potential difference between the ends of a conductor is directly
proportional to the electric current passing through it at constant temperature.
V x IV/I= constant
1) Complete the circuit as shown in figure.
2) Knob should be adjusted to 4.5V at battery.
5.D Verification:
Aim: To verify Ohm’s law or to show that V/I= constant for a Conductor. Materials required: 6V Battery eliminator, 0 to 1A Ammeter, 0 – 6V volt meter, copper wires, 50 cm manganin coil, Rheostat, switch and 3V LED, etc.
Procedure: Calcination S.No. Potential Current V/I

3) Using Rheostat change the potential
difference between two ends of manganin
wire from OV to 4.5V.
4) By using Rheostat adjust the potential
difference 1V between two ends of manganin wire.
5) Now observe the electric current through Ammeter in the circuit and note down in the following table.

14) (b) Froth Floatation process:
1) This method is mainly useful for sulphide ores property whereas which have no wetting impurities get wetted.
2) The ore with impurities is finely powdered and kept in water taken in a floatation cell.
3) Air under pressure is blown to produce froth in water. Ballery Eliminator

1. Using Rheostat change the potential difference with different values up to 4.5V and note down the current value (I) in the table.
2. Take at least five values of V and I and note down in the table and find V/I for each
set of values.
3. We notice that V/I is a constant.
VxI➡V/I= constant
4) Froth so produced takes the ore particles to the surface whereas impurities
settle at the bottom.

5) Froth is separated and washed to get ore
particles.

Conclusion: From this experiment we can conclude that the potential difference
between the ends of the manganin wire is directly proportional to the current passing
through it. Hence, Ohm’s law is verified.
