Question

Keeping in mind what you did in the lab this week, do you think that determining the volumes of your solid samples (rubber stopper, crock stopper, and pennies) by measuring their dimensions and calculating it mathematically would be more or less accurate than determining their volumes by water displacement? Explain.

Answer 1

Answer:

Calculating volumes by water displacement is always more accurate than using mathematical formulas when the objects have irregular shapes or it is difficult to measure them exactly. The only thing that you must keep in mind is measuring the water displacements properly. One ml of water equals 1 cm³, so if the water level increased by 5 ml, then the object's volume is 5 cm³.
