Statement (I) : In order to produce electric power from a geothermal reservoir, temperature above 180° is required. Statement (II) : To drive steam turbines, high temperature steam is used.
General SciencePhysics
- ABoth Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
- BBoth Statement (I) and Statement (II) are individually true but Statement (II) is NOT the correct explanation of Statement (I)
- CStatement (I) is true but Statement (II) is false
- DStatement (I) is false but Statement (II) is true
Explanation
Statement I is true: conventional geothermal power generation requires reservoir temperatures above about 180°C. Statement II is true: steam turbines are driven by high-temperature steam. Statement II explains Statement I, because the 180°C threshold exists precisely to raise the high-temperature steam needed to drive the turbines. Hence both are true and II is the correct explanation of I.
