9:37 ® d y LABORATORY-ACTIVITY-4 - Saved 目 LABORATORY ACTIVITY 4 PHYSICAL PROPERTIES OF MATTER I. OVERVIEW A physical property is a characteristic that can be observed and measured without changing the identity and composition of the substance. Examples of physical properties are color, melting point, and boiling point. Physical properties are very important because these help chemists in identifying substances. For example, a clear, colorless liquid observed to boil at 100 and freeze at OE would definitely be water. Water undergoes physical change wherein its physical appearance changes but its composition remains unchanged. I. ОВIЕСTIVES 1. To be able to determine the physical properties of matter. III. MATERIALS 1 long liwanag candle (remove the tip and cut into 2-inch, 3-inch, and 4-inch long) 3 iron nails (1-inch, 2-inch, and 4-inch long) Water Clear straight glass (calibrate: 1mm = 1 mL) Weighing scale IV. PROCEDURE 1. Describe the hardness and color of the candle and iron nails. Weigh each of the three candles. Record their masses. Fill the glass with 200 ml of water. Get the volume of each candle by determining the amount of water each piece displaces. 2. 3. 4. Repeat steps 2 and 3 for three nails. Solve for the density of each material. 5. V. COMPUTATIONS VI.
