Question

if an object has a definite volume and an indefinite shape, what is it? *
solid
liquid
gas
plasma
what quantity does the following measurement represent: 4.2 g/ml
energy
concentration
mass
density

Explanation:

1. For the first question, liquids have a definite volume as the amount of liquid remains constant, but they take the shape of their container, so they have an indefinite shape. Solids have a definite shape and volume, gases and plasmas have indefinite volume and shape.
2. For the second question, density is defined as mass per unit volume. The unit g/mL is a common unit for density. Energy has units like joules, concentration has units like moles per liter in chemistry - related contexts, and mass has units like grams but not g/mL.

Answer:

1. B. Liquid
2. D. density
