While finding specific heat capacity using calorimeter, error might occur due to:

Options

A. Absence of water equivalent
B. Absence of heat loss reducing covers.
C. Presence of stirrer
D. Absence of stirrer

Answer

A, B

Explanation

Water equivalent is important since the calorimeter also will lose or gain heat. Heat loss has to reduced (by Radiation and//or Convection).
So, choices (`a`) and (`b`) are correct.
Use of stirrer, maintains uniform temperture So, choices (`c`) and (`d`) are wrong.
