The specific heat capacity of a metal at low temperature (T) is given as  A 100 g vessel of this metal is to be cooled from 20 K to 4 K by a special refrigerator operating at room temperature (27°C). The amount of work required to cool in vessel is
  • a)
    equal to 0.002 kJ
  • b)
    greater than 0.148 kJ
  • c)
    between 0.148kJ and 0.028kJ
  • d)
    less than 0.028 kJ
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The specific heat capacity of a metal at low temperature (T) is given ...
Heat required to change the temperatureof vessel by a small amount dT
Work done required to maintain the temperature of sink to T2


As temperature is changing from 20k to 4 k, work done required will be more than W1 but less than W2.
