cup of iced water has 50 g of ice cubes in 100 g of water all at 0 degrees celsius in a room where the air temp if 27 degrees celsius. soemtime later all the ice cubes melt into water still at 0 degrees celsius. what is the change in entropy of A) the iced water? what is the change in entropy for the room and the change in entropy for the "universe"?

Suppose that 100.0 g of ice at 0 degrees Celsius are added to 300.0 g of water at 25.00 degrees Celsius. Is this sufficient ice to lower the temperature of the water to 5.00 degrees Celsius and still have ice remaining? Calculate the energy (heat), which must be removed from water to achieve the desired temperature change, and then prove that there is (is not) sufficient ice to cool the water. Use the specific heat capacity of water (4.184 J/g-*C)...

This problem examines the effects of mixing water at two different temperatures and/or two different phases, such as dropping ice cubes into warm water. Assume that heat of fusion is 333.55 J/g, that CP for ice is constant at 2.11 J/(g·K), and CP for liquid water is constant at 4.19 J/(g·K). You can assume CP approximately equals CV for solids and liquids. For each of the following cases, assume the mixing is adiabatic and carried out at atmospheric pressure. Find...

After a victorious game, George always dreams of a cold cup of water but as his future holds he only has 40.0 g of water at room temperature (25°C). (10 points) How much heat will be released if all the water, 40 g at 25°C, is converted to ice at 0°C. (10 points) If George still has his original cup of 40.0 g of water at room temperature (25°C), determine the composition and temperature of the mixture if George adds...
