Question

define density of a substances with its unit you are given a piece of copper how you will determine its density​

Answer 1

The mass per unit volume is called Density. It means the mass in a per metre cube volume is called density. If a piece of copper is given we can find two by 2 ways.... ... 2.By submerge in water the amount of water displace will be its mass and we can find density from it.

please mark me brain mark list

Answer 2

Answer:

The mass per unit volume is called Density. It means the mass in a per metre cube volume is called density

If a piece of copper is given we can find by 2 ways:

By submerging copper piece in water the amount of water displaced will be its mass and we can find density from it.
