Here's how to perform Activity 12 to investigate the densities of different solid materials: Aim: To investigate the densities of different solid materials. Materials needed: Various metal samples (e.g., iron nail, iron rod piece, lead, aluminium, copper, zinc), balance, measuring cylinder, beaker, water, forceps, scale. Step 1: a) Start by collecting samples of the metals you want to test. Make sure they are clean and free of any dirt or debris. This ensures accurate measurements. Step 2: b) Weigh the mass of each metal sample using a balance and record the mass in grams. This will be the 'Mass' component for the density calculation. Step 3: c) Fill the measuring cylinder with a known volume of water and record this initial volume. This is your starting point for measuring volume displacement. Step 4: d) Carefully lower the first metal sample into the water in the measuring cylinder using a pair of forceps. Make sure the metal is fully submerged without splashing. Step 5: e) Measure and record the new increased volume of water after adding the metal sample. The volume should be measured in ml or cm^3 (where 1 ml = 1 cm^3). Step 6: f) Repeat steps b through e for each metal sample you wish to test. This ensures you have mass and volume data for all samples. Step 7: g) Calculate the volume of each metal sample by subtracting the initial volume of water (from step c) from the final volume of water (from step e). Volume of metal sample = Final volume of water - Initial volume of water Step 8: h) Use the formula: Density = Mass / Volume to calculate the density of each metal sample. Density = MassVolume The unit for density will typically be g/cm^3 or g/ml. That's 2 down. 3 left today — send the next one.
