Question 24

Quantity of Heat

A good calorimeter should be of

  1. A.low specific heat capacity and low heat conductivity
  2. B.low specific heat capacity and high heat conductivity
  3. C.high specific heat capacity and low heat conductivity
  4. D.high specific heat capacity and low heat conductivity
  5. E.dull surface and low heat conductivity.
Show the answer and explanation

Answer: B (low specific heat capacity and high heat conductivity)

Explanation

A low specific heat capacity means the calorimeter takes little of the heat, and high conductivity lets its contents reach one steady temperature quickly.
