Assertion: A high-specific-heat liquid is useful as an engine coolant.
Reason: A liquid with greater specific heat absorbs less heat for the same mass and temperature rise.
Options:
Answer:
C
Solution:
High. The coolant must carry away a large amount of heat from the engine with a small temperature rise and a modest flow; water-based coolants (large ) do this well. Assertion is true, but Reason is false. Correct option: (C).
