Question

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

Answer 1

Answer:

Get a beaker full of water and weigh it. now place the coin inside the water without touching any side of the beaker and weigh the displaced weight as V. Now find out the ratio between the two and that will be the density of the material of the coin. Density .

Explanation:

Using a vernier caliper or ruler, measure the length, depth and width of the object in centimeters. Multiply these three measurements to find the volume in cubic centimeters. Divide the object's mass by its volume to determine its density. Density is expressed in grams per cubic centimeter or grams per milliliter.

Answer 2

To find the density of the material of a coin, we need to find its (i) mass—by common beam balance and (ii) Its volume by measuring cylinder. Measure the mass of coin.

EXPERIMENT – Let the mass of coin shown by beam balance = M (gram) = 50 g (ray) Measure the vol. of the coin. Initial volume of water = V1 = 40 ml (say) Final volume of water When coin is added in the cylinder=V2 = 50 ml (say) Then vol. of coin = V2 – V1 = 50 – 40 = 10 ml
