Processes with negative entropy are fairly common (e.g. water spontaneously freezes below zero degrees celsius). How can such processes occur since spontaneity is associated with positive entropy?
How many calories are required to convert 17g of ice at 0.0 degrees celsius to liquid water at 32.0 degrees celsius. The heat of fusion for water is 80. cal/g
How many grams of ice at -24.9 degrees Celsius can be completely converted to liquid at 5.1 degrees Celsius if the available heat for this process is 4.22x10^3 kJ? For ice, use a specific heat of 2.01J/(gxC) and enthalpy of fusion of 6.01kJ/mol.

A group of students place a 0.045 kg water sample, initial temperature 21.5 degrees Celsius, on a heat source. The water is then warmed up to its boiling point then further heated until it is completely evaporated. Note: Both the heat source and the water are in a thermally isolated container. i. Find the total heat absorbed by the water during this process. ii. A similar experiment is performed on an unknown liquid, mass=0.055kg with initial temperature 21.5 degrees Celsius....
How much heat is released when 15.0 grams of water vapor at 110 degrees Celsius changes to liquid water then to ice at negative 15 degrees Celsius?

Programming Language: C# We all know that water can exist in solid, liquid and gaseous form. Using Visual Studios Write a program that inputs the temperature for water in degrees Celsius, converts the temperature to degrees Fahrenheit according to the formula F = 9.0/5.0 * C + 32.0 and then prints both temperatures to a list box, message box or text box(s). In addition, the program will print the form of water (solid, solid or liquid, liquid, liquid or gas,...
A 5 mole sample of liquid acetone is converted to a gas at 75.0 degrees Celsius. If 628.00 J is required to raise the temperature of the liquid to its boiling point, 15.60 kJ is required to evaporate the liquid, and 712.00 J is required to raise the final temperature to 75.0 degrees Celsius, what is the total energy required for the conversion?
