Answer:
A liquid has a definite volume but not a definite shape
Answer: B. The molecules move faster and become less dense
Explanation:
Liquid is the state of matter in which particles are less tightly bound as compared to solids as they have weak inter molecular forces as compared to solids.
Thus when a solid is heated, the molecules start moving in random motion due to an increase in the kinetic energy. The molecules move apart as the forces will be weak and thus less molecules will be present per unit volume. Thus it will become less dense.
Answer: 2.744 x 1025 molecules
Answer:
the question makes no sense, no products are shown therfore all are reactants.
