1.	250 gm of water and equal volume of alcohol of mass 200 gm are replaced successively in the same calorimeter which cools from 60∘C to 55∘C in 130 seconds and 67 seconds respectively. If the water equivalent of the calorimeter is 10 gm, then the specific heat of alcohol (in cal/g ∘C) is(Assume that rate of heat loss in both the cases remains same)
Answer» $250 gm$ of water and equal volume of alcohol of mass $200 gm$ are replaced successively in the same calorimeter which cools from $60^{\circ} C$ to $55^{\circ} C$ in $130$ seconds and $67$ seconds respectively. If the water equivalent of the calorimeter is $10 gm$ , then the specific heat of alcohol (in ${cal/g}^{\circ} C$ ) is (Assume that rate of heat loss in both the cases remains same)
