Consider two 35-gram ice cubes, each initially at -5°C. One is dropped into a at container filled with 0.1 kg of liquid nitrogen (initially the boiling point of nitrogen); the other cube is dropped into a container filled with 1 kg of (liquid) water, initially at 5°C. Assume that no heat is lost through either container (or into the atmosphere)
a) Describe what happens to each ice cube (and why)
b) If (Lv)Nitrogen =48 kcal/kg, (LF)Nitrogen = 6.1 kcal/kg, and cNitrogen =0.15 kcal/(kg °C), determine how much heat would be needed to produce 100 grams of nitrogen gas at 20°C.
c) Determine the final (equilibrium) temperature of the icewater mixture.
d) Determine the phase (ie., liquid or solid) corresponding to the equilibrium temperature you obtained in part (c).

The potential equals 400 V at 1.00 m from a very large, flat dielectric sheet that carries a surface charge density of -1.00 x 10^-8 C/m2
Let's assume the classifier gives an output y(x), where x is the input, which we won't discuss further, and that the true target value is t. In the simplest discussions of classifiers, both y and t are binary variables, but you might care to consi..
