Question

a state of matter with a definite volume but no definite shape; options: aom, thermal energy, molecule, liquid

Explanation:

In physics (a subfield of Natural Science), the states of matter are studied. A liquid is known to have a definite volume (it takes up a specific amount of space) but no definite shape (it conforms to the shape of its container). "Atom" is a basic unit of matter, "Thermal Energy" is related to heat, and "Molecule" is a group of atoms—none of these match the description of a state of matter with definite volume and no definite shape.

Answer:

1. Liquid
