How can we calculate the volume and mass of the irregular object
Answers
Answer:
The density of something is just the mass divided by the volume:
D = m/V
The mass you can measure on a balance or a scale, and the volume is the amount of space the object occupies. You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up.
You can use this relation backwards too -- if you know what material an object is made of, you can look up its density in a book. Measuring its mass allows you to compute the volume.
Answer:
Hola dear,
Displacement is usually the method that is used to measure the volume of an irregularly shaped object. The object is simply submerged in a liquid and the volume of liquid that is displaced is measured.
Finding the volume of a regular object, such as cube or sphere, is typically done using an equation. Irregular objects like a screw or rock require a more hands on approach. Luckily, there is a straightforward way to calculate the volume of irregular objects using the water levels in a graduated cylinder.
Steps-
Add water to a graduated cylinder.
Read the meniscus.
Record your measurement.
Submerge your object.
Take a new measurement.
Record your final measurement.
Calculating the Volume of Your Object.
Understand the measurements.
Solve for the difference between water levels.
(equation Vtotal - Vwater = Vobject. Vtotal is your final measurement, Vwater is your initial measurement, and Vobject is the volume of your object)
Analyze your answer.
Notes - (If you found a negative volume, it is likely that you simply mixed up the initial and final measurements in your equation and do not need to redo the experiment.
If you obtain a number too large to be reasonable, you either made an arithmetic error or wrote down incorrect measurements. If it is the latter, you will have to redo the experiment.)
Hope it helps.
