Two 20.0 g ice cubes at –16.0 °C are placed into 215 g of water at 25.0 °C. Assuming no energy is transferred to or from the surroundings, calculate the final temperature, Tf, of the water after all the ice melts. heat capacity of H,0(s) 37.7 J/(mol-K) Tf = °C heat capacity of H,O(1) 75.3 J/(mol-K) enthalpy of fusion of H,O 6.01 kJ/mol

What amount of thermal energy (in kJ) is required to convert 221 g of ice at -16 °C completely to water vapour at 214 °C? The melting point of water is 0 °C and its normal boiling point is 100 °C. The heat of fusion of water is 6.02 kJ mol-¹ The heat of vaporization of water at its normal boiling point is 40.7 kJ mol-¹ The specific heat capacity of ice is 2.09 J g-¹ °C-¹ The specific heat capacity of liquid water is 4.18 J g-¹ °C-¹ The specific heat capacity of water vapour is 2.01 Jg¹¹ °C-¹ Answer:

Two 20.0 g ice cubes at -14.0 °C are placed into 295 g of water at 25.0 °C. Assuming no energy is transferred to or from the surroundings, calculate the final temperature, Tf, of the water after all the ice melts. heat capacity of H₂O(s) heat capacity of H₂O(1) enthalpy of fusion of H₂O 37.7 J/(mol.K) 75.3 J/(mol.K) 6.01 kJ/mol Tf= °C

Two 20.0 g ice cubes at -18.0 °C are placed into 215 g of water at 25.0 °C. Assuming no energy is transferred to or from the surroundings, calculate the final temperature, Tf, of the water after all the ice melts. heat capacity of H₂O(s) heat capacity of H₂O(1) enthalpy of fusion of H₂O 37.7 J/(mol-K) 75.3 J/(mol-K) 6.01 kJ/mol Tf = °C

What quantity of heat (in KJ) would be required to convert 11.1 g of ice to water 0.00 C ? (Hfus=6.01 KJ/ mol for water)

Calculate the energy (in kcal) required to convert one ice cube that was made by freezing 72 mL of water (density = 1.000 g/L) an an initial temperature of -36.0 C, to liquid water at a final temperature of 37.0 CH2O(s) --> H2O(l) ΔH = +6.02 kj/mol Cpm H2O(s) = 37.7 J/mol x K  Cpm H2O(l) = 75.4 J/mol x K  1 kcal = 4.18 kJ
