Question

what are three errors when it comes to measuring the density of solids an liquids?

Answer 1

1. Density varies with temperature. Though considerations may or may not be negligible. Density at one temperature may not be valid at other. Liquid will have different density at diff. Temp.

2. If a solid is regular in shape like cube, cylinder ,cuboid, spherical etc we can easily calculate its volume, but the instruments used to do the measurements should be accurate. However, if it is irregular in then the calculation of its exact volume is difficult and hence also its exact density can't be found.

3. If you find the volume of irregular solid using archimedes principle than it into be kept in mind that solid may not absorb water and may make error in calculation s.
