The following article will add knowledge about “Why is density a physical or chemical property?“. Let’s not forget to look at the content!
Why is density considered a physical property rather than a chemical property of matter?
Answer “Why is density a physical or chemical property?”.
Properties of Matter:
There are two types of properties in matter: chemical and physical. It is possible to observe or measure a physical property without exposing matter to a chemical reaction which transforms it into another one. A chemical property, on the other hand can only be measured or observed once a matter has been allowed to change its structure.
It’s a measure of the mass per volume. The object’s average density is its total mass divided with its volume. A object made of a dense material will have fewer volumes than one made from a less dense substance. The units used to measure density are grams per cubic meter.
The formula of density is D = m / V .
Density can be described as a property of matter. It is an intensive property. An intensive property is the ratio between two properties of the same object or system. It has a narrow range for densities. It is an intens property because it doesn’t depend on the amount of material. Density is a physical property.
It is possible to measure the mass of an object without altering its composition. The same applies to an object’s volume. This property is a physical property, meaning that it does not require a chemical reaction to measure the object’s density.
a. You can express the density of an object in units of kg/L or in units of g/mL. How is the density of an object in kg/L related to its density in g/mL?
b. You are given a sample block of an unknown metal. The block displaces 3.24 mL of water and has a mass of 62.5429 g. What is the density of the unknown metal? What is the metal?
a. SI unit of density is Kilogram per cubic meter. is equal to 0.001g/ml or 0.001kg/L. A mass of 1 kg was set equal to 1L volume of water. Therefore density of water is 1Kg/L . A density of 1Kg/L is exactly equivalent to 1g/ml.
Volume of metal is 3.24ml and mass is 62.5429g. The mass per volume is the measure of a metal’s density.
So, the density of metal is 19.30g/ml. The metal is gold. Gold has a density of 19.30g/ml.
