Steam at 100 °C is bubbled into 2.70 kg of water at 25 °C in a calorimeter cup. How much steam will have been added when the water in the cup reaches 55 °C? (Ignore the effect of the cup.)
Initial mass of water
Mass of steam converted to water =
Initial temperature of water
Final temperature of water
Specific heat of water
Latent heat of vaporization of water
Water in the cup is heated from to .
Steam undergoes change of state at and cools from to
Heat required to raise the temperature of water from to
Heat released by steam during change of state
Heat released by added water during cooling from to
Since Heat Lost is equal to Heat gained,
