select
is a state of matter where the particles are closely packed together with a definite shape and volume.
select
is a state of matter that has a definite volume but takes the shape of its container (indefinite shape).

Explanation:

Question 12

The question is about a property of materials related to shininess. Luster is the property that describes how shiny a material is. Conductivity is about heat/electricity transfer, ductility about being drawn into wires, and malleability about being hammered into sheets. So the correct option is luster.

A liquid has a definite volume but takes the shape of its container (indefinite shape). Solids have definite shape and volume, gases have indefinite shape and volume. So the state is liquid.

A solid has particles closely packed, definite shape and volume. Liquids have definite volume but indefinite shape, gases have neither definite. So the state is solid.

Answer:

B. luster (assuming the options are ordered as: A. conductivity, B. luster, C. ductility, D. malleability; if the original option order is different, adjust the identifier but the text is luster)
