Which best explains the statement "it has no definite volume”? a. its atoms can widely spread out. b. its atoms stay closely packed. c. it’s highly viscous. d. it’s highly crystalline.

Answer With Explanation:

The term no Definite volume means things which can't be kept in a container which has fixed mass.For Example Water in a Flowing River can be called as "No Definite volume"  because Quantity of water can't be measured in the flowing river.

⇒If Atoms are closely packed , it can be kept in a container and we can describe it in terms of Volume.

⇒If Liquid is Viscous , it means it is in Solid State ,so it can be Described in terms of Volume ,because A fixed shape has mass And Mass is related to Volume.

⇒Crystals are solids.Solids has Volume.

⇒Option A is Incorrect.⇒Its atoms can widely spread out

If Atoms are Widely Spread out, it can't be packed in a container.So it doesn't has fixed or definite volume.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
