Calorimetry PrincipleHardQuestion 30859

Question

A calorimeter problem: if specific heat of a solid is determined by method of mixtures, the main source of error is:
  1. A
    Radiation loss from calorimeter
    Correct
  2. B
    Mass measurement error
  3. C
    Using wrong thermometer
  4. D
    Colour of calorimeter

Correct answer

Radiation loss from calorimeter

Explanation

Heat exchange with surroundings (radiation, convection) violates the isolated-system assumption, introducing systematic error.
