Describe an experiment to determine the density of the material of a coin.

The density of the material of a coin is determined by the following experiment: 1. We know density is mass per unit volume. So, first mass of the coin is measured by a common beam balance. Let it be M gram. 2. Volume of the coin is measured by a measuring cylinder as shown in the figure given below. 3. Take a measuring cylinder and fill it partly with water. 4. Note the level of water. Let it be V 1 mL. 5. Tie the coin with a thread and gently lower the coin inside the measuring cylinder. Take care that no water splashes out. 6. Note the level of water again. Let it be V 2 mL. 7. Find the volume of the coin (V) by subtracting V 1 from V 2 . V = V 2 - V 1 Density of coin is calculated by the formula:
