To test for fat using alcohol and cold water, you would first dissolve the sample suspected of containing fat in warm alcohol, which helps dissolve the fat. Afterward, you would add cold water to the alcohol solution; if fat is present, it will form a cloudy emulsion or separate out, indicating the presence of fat. This method works because fats are not soluble in water, leading to a visible reaction.

Why test tube must place in a cold of water when distillation happens?
During distillation, the test tube is placed in cold water to facilitate the condensation of vapor back into liquid. As the vapor rises and reaches the cooler surface of the test tube, the cold water helps lower the temperature, allowing the vapor to condense efficiently. This process ensures that the desired distillate is collected in liquid form rather than escaping as vapor, improving the yield and purity of the distilled product.
