Something soundproof or near sound proof. A vacuum, for example.
The last time I checked the worst conductor of electricity is rubber.
The best conductor of heat is silver, followed by copper and aluminum. The worst conductor of heat is typically materials like wood, paper, and plastic.
Silver is one of the best conductors of electricity due to its high electrical conductivity. In contrast, rubber is one of the worst conductors of electricity because it is an insulator and does not allow electrical current to flow easily.
Gas is a good conductor of sound because its molecules are further apart compared to solid and liquid molecules, allowing sound waves to travel through with less interference. This means that the vibrations from sound can easily pass through the gas medium, making it an effective conductor of sound.
Rubber is an insulator of sound, as it dampens and absorbs sound waves rather than allowing them to pass through. Rubber is a poor conductor of sound due to its molecular structure, which hinders the transmission of vibrations.
Aluminium is a good conductor of heat.
No.

Air is a good conductor of sound, and a poor conductor of heat and electric current.
