Liquid is filled in a vessel which is kept in a room with temperature 20 C When the temperature of the liquid is 80 C then it looses heat at the rate of 60 cal/s. What will be the rate of loss of heat when the temperature of the liquid is 40 C

An open-system chemostat technique was employed to study temperature and precipitation rate effects on carbon isotopic fractionation during the inorganic precipitation of aragonite and calcite from solutions held at constant chemical and isotopic composition. Calcite-bicarbonate enrichment factors (ϵcl-HCO−3) average 1.0 ± 0.2%. and are essentially constant throughout the range of temperatures (10, 25, and 40°C) and precipitation rates (1026 to 104.8 μmol m−2 h−1) studied. Calcite-CO2(g) enrichment factors (ϵcl-CO2) are temperature sensitive and are described by the equation ϵcl-CO2 = 11.98(±0.13) −0.12(±0.01
We know that,
Q/t α (T2 – T1)
So,
[(Q/t)1]/[(Q/t)2] = [(80 – 20)]/[(40 – 20)]
[(Q/t)2] = 20 cal/s
Hence, correct option is 4
