What happens to the density of a material if you have a larger piece of it?
A)The density will remain the same because mass and volume will remain the same.
B)The density will be greater because the mass increases but the volume remains the same.
C)The density will be smaller because the mass remains the same as the volume increases.
D)The density will remain the same because mass and volume will both increase in the same way.
D is the best answer there but I would like it to be stated in a slightly different way. The density will be the same because both the mass and volume increase proportionally; i.e. density = mass/volume so if the mass is doubled the volume is doubled also and the density doesn't change.
A) The density will remain the same because mass and volume will remain the same.
To answer this question, we need to understand the concept of density. Density is defined as the ratio of the mass of a substance to its volume. It is a property that helps us determine how closely packed the particles are in a material.
Given that we have a larger piece of the material, we can analyze the options:
A) The density will remain the same because mass and volume will remain the same.
This option assumes that both the mass and volume of the material will stay constant. However, since we have a larger piece of the material, the volume will actually increase, making this option incorrect.
B) The density will be greater because the mass increases but the volume remains the same.
This option acknowledges that the mass will increase while the volume remains unchanged. Since density is the ratio of mass to volume, if the mass increases while the volume remains the same, the density will indeed become greater. This is due to there being more mass packed into the same volume, resulting in a higher density. Therefore, this option could be the correct answer.
C) The density will be smaller because the mass remains the same as the volume increases.
This option assumes that the volume increases while the mass remains constant. However, if the mass remains the same and the volume increases, the density will actually decrease. More volume with the same amount of mass means the particles are less closely packed, thus resulting in a lower density. Therefore, this option is incorrect.
D) The density will remain the same because mass and volume will both increase in the same way.
This option assumes that both the mass and volume will increase proportionally. However, even if both increase, the density can still change depending on the ratio between the two. Since this option assumes they increase in the same way, it fails to consider the influence of the ratio. Therefore, this option is incorrect.
Based on the above analysis, the correct answer is B) The density will be greater because the mass increases but the volume remains the same.
