Answer:

silicon carbide (SiC), a network solid

Explanation:

SiC has a giant network of covalent structure which takes a lot of energy to break than just a single covalent bond. In the network there are many Si and C atoms. All the atoms in the network are linked to each other by strong covalent bonds. SiC forms a lattice structure, in which both the Si and C atoms are sp³ hybridized. In the SiC crystal lattice the smallest unit is a tetrahedron of a central Si atom surrounded by four C atoms or a central C atom surrounded by four Si atoms.

Which of the following will stay constant, no matter if the substance is in the solid, liquid, or gas state? volume shape temper
Harman [31]

Answer : The correct option is, Mass

Explanation :

As we know that there are 3 states of matter :

Solid state : It is a state in which the particles are closely packed and does not have any space between them. This state have a definite shape and volume.

Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. This state have a definite volume but does not have a fixed shape.

Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them. This state have indefinite volume as well as shape.

If we are taking 100 grams of ice then after melting its mass remains same but its shape, volume and temperature will be changed and after evaporation its mass remains same but its shape, volume and temperature will be changed.

Hence, the mass will stay constant, no matter if the substance is in the solid, liquid, or gas state.
