A scientist is creating a new synthetic material. The material’s density is 6.1 g/cm3. Which sentences describe how the scientist can lower the material’s density?

A. The scientist can decrease the mass while keeping the volume constant.
B. The scientist can increase the mass while keeping the volume constant.
C. The scientist can decrease the volume while keeping the mass constant.
D. The scientist can increase the volume while keeping the mass constant.

Respuesta :

a sounds like the best answer

Answer:

A. The scientist can decrease the mass while keeping the volume constant.

D. The scientist can increase the volume while keeping the mass constant.

Explanation:

The given density is 6.1 g/cm³

Density is related to mass and volume as:

[tex]density=\frac{mass}{volume}[/tex]

As given that 1 centimeter cube of material has mass of 6.1 grams.

The decrease in density means, that either the mass should be decreases or the volume should be increased.

hence

A. The scientist can decrease the mass while keeping the volume constant.

D. The scientist can increase the volume while keeping the mass constant.
