Steam at 100C is added to ice at 0C.The mass of the steam is 10g.The mass of ice is 50g. What is the final temperature of the mixture?
I know the conversion of steam to water is Ms(2.26x10^6J/kg)
How does this problem work?
1. An iron all of 1500 gm, mass and temperature 100°C is dropped into the cavity of a large block of ice. If specificheat of iron is 0.11, how much ice will be melted?
2. How much heat is generated, if 230g of ice at is melted at 10°C find the resulting water boiled and formed into steam at 120°C, [Specificheat of ice, i
5.2 Calculate the entropy change for each of the following:
(a) 10g of steam at l00°C and a pressure of one atmosphere condensing into water at the same temperature and pressure. (The latentheat of vaporization of water is 22571 Jg^-1).
(b) 10g of water at l00°C and a pressure of one atmosphere cooling to 0°C at the same
How much heat (energy) is required to convert 52.0 g of ice at -10.0 degree C to steam at 100 degree C?
specificheat of ice: 2.09 J/g degree Celsius Delta H fus
specificheat of water: 4.18 J/g Celsius Delta H vap= 40.7 kJ/mol
specificheat of steam: 1.84 J/g Celsius
Calculate the amount of heat that must be absorbed by 10.0 g of ice at -20.0 degrees C to convert it to liquid water at 60.0 degree C.
Specificheat (ice) = 2.1 j/g degree C
Specificheat (water) delta H (fus)= 6.0 kJ/mol
If we add 10 grams of steam at 100 C to and 0.5 grams of ice at 0 degree C to 170 grams of water at 25 C, what will be the final temperature of the mixture, assuming that all thermal exchanges take place within this system? The heats of vaporization and fusion for water are about 2250 J/gram and 335 J/gram.
100 g of ice is melted at 0 degree C, and the resulting water is warmed to room temperature (25 degree C). Calculate delta S (change in entropy) for this whole process and comment on the relative magnitude of the entropy changes for the two steps. Explain the sign of delta S.
How many kilojoules of heat are required to melt an ice cube having the dimensions 3.8 cm x 2.8 cm x 2.1 cm? The density of ice is 0.92 g/cm^3 (cubed). Refer to table:
