Answer 2

Assertion: Copper is used to make hot water tanks and not steel.

Reason: Copper is a better conductor of heat than steel and it is fairly resistant to  corrosion than steel.

Both A and R are true and R is correct explanation of the assertion.

• Option (a) is correct.
• (a) Copper does not corrode easily than steel as steel is an alloy of iron, the iron reacts readily with water than copper and makes the tank weaker in accordance with stability.
• (b) Copper does not corrode and even it has a high melting point, which makes it maintain the temperature of water high when boiled. An oxide layer gets formed due to reaction of steel with air.
