Question

Walls made of paraffin wax, a covalent compound, help keep the temperature in a room steady as night changes into day and day into night. What is the most important property of covalent compounds that allows paraffin wax to help keep a room’s temperature level? The wall would not absorb or release any heat energy from the room or outside, so it would not affect the room’s temperature. The wall would not absorb heat during the day, but at night it would release heat that naturally exists inside of most covalent compounds. The wall would absorb extra heat during the day when the sun is out, then release the heat back into the room when the sun goes down. The wall would absorb extra heat during the day, and the wall would hold this heat in so that it cannot absorb any more heat from the night air.

Answer 1

The wall would absorb extra heat during the day when the sun is out, then release the heat back into the room when the sun goes down.

Answer 2

Answer: Option (c) is the correct answer.

Explanation:

Covalent compounds are the compounds in which atoms combine by sharing of electrons.

These compounds have weak forces of attraction and therefore, they easily heat up and thus, have low melting and boiling point.

Hence, the most important property of covalent compounds that allows paraffin wax to help keep a room’s temperature level is that the wall would absorb extra heat during the day when the sun is out, then release the heat back into the room when the sun goes down.
