Question

A volume of 120 ml of drink (half alcohol + half water by mass) originally at a temperature of 25°c is cooled by adding 20 gm of ice at 0°c. If all the ice melts, find the final temperature of the drink. (Density of drink = 0.833 gm/cc, specific heat of alcohol = 0.6 cal/gm.°c, specific heat of water = 1 cal/gm.°c, specific latent heat of ice = 80 cal/gm)

Answer 1

A volume of 120 ml of drink (half alcohol + half water by mass) originally at a temperature of 25°c is cooled by adding 20 gm of ice at 0°c. If all the ice melts, find the final temperature of the drink. (Density of drink = 0.833 gm/cc, specific heat of alcohol = 0.6 cal/gm.°c, specific heat of water = 1 cal/gm.°c, specific latent heat of ice = 80 cal/gm).
The answer to the given question is 4-degree centigrade.
