If the volume of an object increases but the mass stays the same, which will happen to the density?
2 answers:
Answer: density will decrease.
Explanation:
Density is defined as the mass contained per unit volume.
where ,
= Density of the object
m= Mass of object
v= volume of the object
As density is inversely proportional to volume, if volume of an object increases, the density of the object decreases when mass remains the same.
Thus the density of the object decreases if the volume of an object increases but the mass stays the same.

The most accurately represented John Dalton's model of the atom is: C. a tiny, solid sphere with a predictable mass for a given element
<h3>Further explanation</h3>The development of atomic theory starts from the first term conveyed by Greek scientists who suggested that every substance has the smallest particles so that the word atomos appears, which means it cannot be divided. So, John Dalton, a British scientist put forward the hypothesis about atoms, among others:
- 1. The elements are composed of atoms which are small particles which cannot be subdivided
- 2. Atoms that make up the same element have the same properties, mass, and size, while for different elements, the properties are also different
- 3. Compounds are composed of two or more atoms in a fixed ratio
- 4. In chemical reactions, atoms after and before a reaction cannot be destroyed, only separation and reassembly occur
Point 3 shows the relationship with The Law of Constant Composition of Proust so that further research on atoms is more developed
Dalton's hypothesis is described as a solid sphere like a very small shot put ball or a bowling ball based on Dalton's hobby in bowling
