Identify why, in the image below, object C has the greatest mass. It has the most particles.1Its particles are hotter.2It is square.3Its particles are larger.4

To determine why object C has the greatest mass, let's analyze the provided options:

1. It has the most particles. - This option is correct; mass is directly related to the number of particles in an object given that they have similar properties.
2. Its particles are hotter. - Temperature affects energy and speed of particles but does not directly relate to mass.
3. It is square. - The shape of an object does not determine its mass; mass is dependent on the material and number of particles.
4. Its particles are larger. - The size of particles can influence mass, but it's more about the number of particles. Larger particles could relate to fewer overall particles for the same mass.

Based on this analysis, the reason why object C has the greatest mass is because it has the most particles.

Final Answer

Object C has the greatest mass because it has the most particles.
