Freezing point depression is the difference between 0°C and the temperature at which an ice cream mix first begins to freeze. Learn about Freezing Point Depression Here.
Melting/freezing point apparatus (1) includes means (9) for measuring the change in reflected light from the surface of a substance (7) at the melting point. The apparatus (1) includes a heating block (2) adapted to house a sample plate (4), a light source (8) and a light detector...
Hint: Freezing point is defined as the temperature where the liquid and solid phases are in equilibrium. Step 3: Draw the Vapor Pressure Curve1. Axes: Start by drawing a graph with the y-axis labeled as "Vapor Pressure" and the x-axis labeled as "Temperature (K)".2. Pure Solvent Line...

If that is a sharp curve, you know the point fairly precisely from graph of your data points. But if you terminate the experiment at 0C, you can't possibly pinpoint the time when the water is completely frozen, at least not with a graph of temperature. Logged A 3.5 digit 4.5 digit...
By the way, interesting to bring up one point here.Calories (with capital C used for food) is 1000x calories (lower case C used in Physics). Some "food science" people must have needed glasses when they first adopted the Physicist's unit of calories. Someone must have mixed upgandkgby...
The error caused by this approximation should be quite small, but it does point to some of the limitations of the activity model approach: 1) limited accuracy of predictive modes for generating key interaction parameters through UNIFAC or similar means, 2) difficulties in handling supercritical ...
