Which statement best describes the structure of covalent network solids? A. They are giant structures held together by weak forc

konstantin123 [22]

Answer: Option (B) is the correct answer.

Explanation:

A covalent compound is a compound formed by sharing of electrons. And, in a covalent network solid atoms are bonded by covalent bonds in a continuous network that is extending throughout the material or solid.

This continuous arrangement of atoms are like a lattice.

For example, diamond is a covalent network solid in which carbon atoms are arranged in a continuous lattice like structure.

Hence, we can conclude that the statement all the atoms are covalently bonded to other atoms to form a lattice-like structure, best describes the structure of covalent network solids.

How does heat differ from temperature?

mote1985 [20]

Answer: Option (c) is the correct answer.

Explanation:

Temperature is used as for measuring the average kinetic energy present in a substance or object.

The internal kinetic energy obtained by the molecules of an object is known as thermal energy.

Hence, temperature measures the thermal energy of an object.

Whereas when this thermal energy flows from a hotter object to a cooler object which are placed adjacent to each other then it is known that heat is flowing.

Thus, we can conclude that heat differ from temperature as temperature measures thermal energy, and heat is the flow of thermal energy.

A ridged steel tank filled with 62.7L of nitrogen gas of 85.0L atm

mylen [45]

The final gas pressure : 175.53 atm

<h3>Further explanation</h3>

Maybe the complete question is like this :

A ridged steel tank filled with 62.7 l of nitrogen gas at 85.0 atm and 19 °C is heated to 330 °C while the volume remains constant. what is the final gas pressure?

The volume remains constant⇒Gay Lussac's Law

When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature

$\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

P₁=85 atm

T₁=19+273=292 K

T₂=330+273=603 K

$\tt P_2=\dfrac{P_1\times T_2}{T_1}\\\\P_2=\dfrac{85\times 603}{292}\\\\P_2=175.53~atm$
