276229 The energy conversion involved in a galvanic cell is

1 Chemical energy to mechanical energy

2 Chemical energy to electrical energy

3 Electrical energy to chemical energy

4 Electrical energy to thermal energy

Explanation:

The energy conversion involved in a galvanic cell is chemical energy into electrical energy.
Galvanic cell consists of two segment box called half cell. The half cell contains electrode and electrolyte solution that is connected in the circuit.
Two dissimilar metals [eg $\to$ copper and zinc] are immersed in electrolyte. These metals are connected by external circuit then one metal (copper) is reduced and other metal [zinc] is oxidized.

276255 A device that converts energy of combustion of fuels like hydrogen and methane, directly into electrical energy is known as

1 dynamo

2 Ni-Cd cell

3 fuel cell

4 electrolytic cell

Explanation:

Fuel cell converts energy of combustion of fuels like $H_{2}, {CH}_{4}$ etc. directly into electrical energy.
Dynamo produce direct current by using a commutator. $Ni - Cd$ cell is a type of rechargeable battery which consists of a cadmium anode and a metal grid containing ${NiO}_{2}$ acting as a cathode.
