I. FREEZING POINT LOWERING: Some crushed ice was placed in a 400 mL beaker. Some of the ice was allowed to melt before the temperature was taken and recorded to be 0°C as temperature of the ice. A 20 % urea solution is accurately prepared from dissolving 2 grams urea in 8 grams of distilled water. This urea solution is placed in a test tube then submerged in the beaker with crushed ice. The temperature of the urea solution was taken three times(3X) at intervals of 30 seconds and was recorded to be -2°C, -4°C and -8°C respectively. The temperature was taken until the freezing point was reached indicated when 3 consecutive temperature readings were identical to be -8°C. This was recorded to be the freezing point of the solution.
