Question

A liquid A has specific heat capacity higher than the liquid B. Which liquid can be used as a coolant in car radiators?

• A. A
• B. B
• C. Both can be used
  
• D. Data insufficient
  

Answer 1

The correct option is A A

A, because it will absorb more heat. In coolant we prefer liquid that can absorb more heat without much change in temperature .

$\Delta T=Q/mc$

So, higher the specific heat capacity c, lesser the $\Delta T$.
