Statement 1: Mostly metals like copper, iron and aluminium are used to...
Statement 1: Mostly metals like copper, iron, and aluminium are used to make the solar heating pipes and boilers in chemical and textile industries.
Statement 2: Copper, iron, and aluminium are good conductors of electricity.

Explanation:
The given statements are related to the use of metals in solar heating pipes and boilers in chemical and textile industries and the conductivity of copper, iron, and aluminium.

Statement 1: Mostly metals like copper, iron, and aluminium are used to make the solar heating pipes and boilers in chemical and textile industries.

Explanation:
Solar heating pipes and boilers used in chemical and textile industries are designed to efficiently transfer heat. Metals like copper, iron, and aluminium are commonly used for this purpose due to their excellent thermal conductivity. These metals allow heat to pass through them quickly, making them suitable for applications that involve the transfer of heat, such as solar heating systems. Therefore, statement 1 is true.

Statement 2: Copper, iron, and aluminium are good conductors of electricity.

Explanation:
Copper, iron, and aluminium are indeed good conductors of electricity. Conductivity is the ability of a material to allow the flow of electric current. Metals, in general, are good conductors of electricity because they have free electrons that can move easily within the metal lattice when a potential difference is applied. Copper is an excellent conductor of electricity and is widely used in electrical wiring. Iron and aluminium also have good electrical conductivity, although not as high as copper. Therefore, statement 2 is true.

Conclusion:
Both statement 1 and statement 2 are true. Metals like copper, iron, and aluminium are used in solar heating pipes and boilers due to their excellent thermal conductivity. They are also good conductors of electricity. However, statement 2 is not the correct reason for statement 1. The use of these metals in solar heating pipes and boilers is primarily due to their thermal conductivity, not their electrical conductivity. Therefore, the correct answer is option C - Both statement 1 and statement 2 are true, but statement 2 is not the correct reason for statement 1.
