Question

Equal volumes of water and alcohol when put in similar calorimeters take 100 sec and 74 sec respectivel<br />to cool from 50°C to 40°C. The thermal capacity of each calorimeter is numerically equal to the volum<br />of either liquid. The specific gravity of alcohol is 0.8. if the specific heat capacity of water is 1 cal/gm-'<br />the specific heat capacity of alcohol will be<br />1) 0.6cal/gm-°C 2) 0.8cal / gm -°C<br />3) 1.6cal/gm-°C 4) 1.8cal /<br />Key<br />gm-°C<br />28.​
