Question

HEY MATE!


* how does the density of liquid (or gas) vary with temperature?

* The density of brass is 8.4 g cm-³ . what do you mean by this statement?​

Answer 1

Answer:

1. Density is the ratio of mass to volume. When the temperature varies, the volume of the liquid changes. ... Also, cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density.

__________________________

2.This implies that for 1 cubic centimeter, the mass of the brass is 8.4 grams. The density is defined as ratio of the mass and volume of the substance . Here , the density of the brass is 8.4g/cm^3 .
