A calorimeter of water equivalent `6g` has water of mass `64g` up to a certain volume An other identical calorimeter has liquid of mass 5g and specific heat `0.6 calg^(@)C` upto same level If both pf them cool in the same surroundings through same range of temperature and the time taken for the water to cool is `140s` the time taken for the liquid to cool is .

A calorimeter of water equivalent 5g has water of mass 55g upto a certain level Another identical calorimeter has a liquid of mass '38g' upto same level As both of them cool in the same surrounding from 50^(@)C to 46^(@)C water takes 80s where as the liquid takes 32s to cool. If the specific heat of water is 1cal//g-.^(@)C the specific heat of the liquid in cal//g-.^(@)C is .

In a calorimeter of water equivalent 20 g, water of mass 1.1 kg is taken at 288 K temperature. If steam at temperature 373 K is passed through it and temperature of water increases by 6.5^(@)C then the mass of steam condensed is

A calorimeter of water equivalent 10 g contains 100 g of water at 90^(@)C . On exposure to air, its temperature falls to 80^(@)C in 5 min. If the same calorimeter is filled with 50 g of an oil, the time for the same drop in temperature is 2 min. Calculate the specific heat of the oil if the rate of heat loss in both the cases is assumed to be the same.

A calorimeter has mass 100g and specific heat 0.1 kcal//kg^(@)C . It contains 250 g of liquid at 30^(@)C having specific heat of 0.4 kcal//kg^(@)C . If we drop a piece of ice of mass 10 g at 0^(@)C , what will be the temperature of the mixture ?
