z.hopts) How much energy(in kJ) must be removed from 71.8g of liquid water at 25.7°C to ice at -16.1°C? Given: Heat of fusion of water = 333J/g 71081 25.7--161 Ice specific heat capacity = 2.06 J/gK water specific heat capacity = 4.184 J/gK
How much heat energy is required to convert 15.0 g of solid
ethanol at -114.5 °C to gasesous ethanol at 143.1 °C? The molar
heat of fusion of ethanol is 4.60 kJ/mol and its molar heat of
vaporization is 38.56 kJ/mol. Ethanol has a normal melting point of
-114.5 °C and a normal boiling point of 78.4 °C. The specific heat
capacity of liquid ethanol is 2.45 J/g·°C and that of gaseous
ethanol is 1.43 J/g·°C.

Calculate the amount of energy needed to heat 346 g of liquid water from 0°C to 182°C. Assume that the specific heat of water is 4.184 J g-1 °C-1 over the entire liquid range and that the specific heat of steam is 1.99 J g-1 °C-1 ; ΔvapH (H2O) = 40.8 kJ mol-1 Please show your method. Thank you!
A 61.93 gram sample of iron (with a specific heat of 0.450 J/g °C) is heated to 100.0 °C. It is then transferred to a coffee cup calorimeter containing 40.6 g of water (specific heat of 4.184 J/ g °C) initally at 20.63 °C. If the final temperature of the system is 23.59, what was the heat absorbed (q) of the calorimeter? (total heat absorbed by the water and calorimeter = heat released by the iron)
