1. calculate the minimum amount of energy (per unit mass) that must be removed from a gallon of milk initially at 40F to cause it to freeze completely. Answer should be in BTU/lbm. 2. what is the percent error involved in treating saturated vapor water as an ideal gas when estimating its specific heat volume at T=243F?
When water vapor condenses to a liquid, must heat be added or removed to maintain a constant temperature?

Using the provided data, calculate the amount of heat, in kJ, that must be removed to cool 22.9 g of gaseous water, initially at 122. °C, to solid water at -29. °C. water molar mass 18.0153 g/mol melting point 0. °C boiling point 100. °C ΔHfus 6.02 kJ/mol ΔHvap at bp 40.7 kJ/mol Cs, solid 2.09 J/g⋅°C Cs, liquid 4.18 J/g⋅°C Cs, gas 1.87 J/g⋅°C
how many joules of energy must be absorbed by 500g of H2O at 50.0 Celcius to convert it to steam at 120 celcius?the molar heat of vaporization of water is 40.7 kj/mol and the molar heat capacities of liquid water and steam are 75.3 j/mol celcius and 36.4 j/mol celcius respectively
How much heat energy in joules must be added to 78 grams of water initially at 23 degrees Celsius if it ends up at 53 degrees Celsius. Remember that the specific heat capacity of water = 4186 J/ (kg oC) or 1 calorie / (g oC)
When significant amount of heat is removed from liquid, the liquid will change from liquid to solid. What energy has decreased in liquid? a) Work energy b) Potential energy c) Kinetic energy d) Internal energy?
Using the provided data, calculate the amount of heat, in kJ, that must be removed to cool 18.8 g of gaseous water, initially at 110. °C, to solid water at -12. °C. water molar mass 18.0153 g/mol melting point 0. °C boiling point 100. °C ΔHfus 6.02 kJ/mol ΔHvap at bp 40.7 kJ/mol Cs, solid 2.09 J/g⋅°C Cs, liquid 4.18 J/g⋅°C Cs, gas 1.87 J/g⋅°C 40.8 kJ 67.7 kJ 37.9 kJ 57.4 kJ 16.3 kJ
Must the amount of heat absorbed as 1 kg of saturated liquid water boils at 100 °C, be equal to the amount of heat released as 1 kg of saturated water vapor condenses at 100 °C? Why? Which process requires more energy: completely vaporizing 1 kg of saturated liquid water at 1 atm pressure or completely vaporizing 1 kg of saturated liquid water at 8 atm pressure? Why? A food-scientist is cooking three identical beef stews in pans that are...
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
